Hello Apple Developer Community, I am reaching out for insights regarding an issue we're facing with Apple Push Notification Service (APNS). Despite successful implementation and functioning for other apps, we are consistently receiving a 400 TopicDisallowed error when trying to send push notifications to one specific app. Here's a detailed overview: Issue Summary: Push notifications sent from our server to a specific app result in a 400 TopicDisallowed error from APNS. This problem is unique to this app; notifications to other apps with similar configurations are successful. Successful Tests via Apple CloudKit Console: Notably, when using the Apple CloudKit Push Notification Console, push notifications to the problematic app are sent successfully, indicating the app's basic setup is configured correctly. Key Details: The topic field in the push notification request matches the app's bundle ID exactly. The app is downloaded from the App Store, and we are using the production environment on our server. Payload structure, APNS endpoint, and APNS Auth Key are consistent across all apps we manage. Device tokens for the problematic app validate successfully using the tool in the push notification console. Detailed server-side logging has not revealed significant differences between successful and unsuccessful push notification requests. Given these factors, we are struggling to identify the root cause of this specific issue. I am wondering if anyone in the community has faced a similar problem or could offer any insights. Any help or guidance would be immensely appreciated. Thank you in advance!

Hello. I have a very practical problem. A company would like me to develop an iOS app for them, and my counterpart is their company's marketing team. They want me to use their Firebase account for multiple purposes, but as they are marketing team, not IT team, they do not have Apple Developer account. So in this peculiar case, as I am the developer of the app, it seems they will need my p8 key to be placed in their Firebase account in order for Push notification to work. But I have concern as p8 key sounds like something private which I should not share with others. Can anyone share with me what I should do in this very practical case? Is p8 key supposed to be sharable to others? I have tried to google this topic but I don't have any answers. I have even tried to ask on stackoverflow but admin over there said this question is opinion-based and closed my thread.

I noticed that the numbers given for the individual states do not add up; i.e. if I add everything other than "Received by APNs" I get what amounts to ~95% of that. Is that expected? And if so what happened to the remaining 5%?

In iOS 17.2 we can start a live activity by push, and the document says: When the system receives the ActivityKit push notification on a device, it starts a new Live Activity, wakes up your app, and grants it background run time to allow you to download assets that the Live Activity needs. My problem is, in which callback can I be notified a live activity will be start by a push, so I can download some web contents such as images before the live activity be rendered.

Sending push notifications does not work. The notification does not arrive, the loading hangs endlessly. Yesterday everything was fine with push notifications, but today they stopped coming. Has anyone come across what could be the problem?

When I try to create a developer account, it says there is some issue with the account and wont allow me to proceed. Please help me resolve the issue.

FCM Push notifications stopped working on PWA for users with the latest version of iOS 17.4.1

Has anyone had problems downloading a newly created APNS key? The first key I made downloaded fine. I realised I had made it on the wrong team, so I revoked it, changed team and made a new key. The first time I clicked Download, it said the key had already been downloaded. I suspected the problem was that I had named it the same as the one I had made in error, so I revoked that new key, and made a new one with a different name, but it still wouldn't download. Has anyone had this? Any workarounds? Thx.

there are any way to force personal access point section as apn mobileconfig?

在项目中用到live activity，并且使用pushnotification来更新，其中sound是用自定义的，音频差不多5秒导入主工程中main bundle ，然后测试远程推送的Payload格式如下 { "aps": { "timestamp": 1712964986737, "event": "update", "sound": "socReminder10.mp3", "content-state": { "bindTime": 1712963986737, "soc": 38, "status": 1, "updateTime": 1712963986737 }, "alert": { "title": "电量低提示", "body": "您的电量已经低于40，请尽快换电" }, "mutable-content": 1, "badge": 0 } } 虽然收到推送的消息并更新但是声音还是默认的声音，不是我定义的声音，请问这个有没有什么解决方案 对了在正常的推送中是可以播放自定义的声音，唯独是live activity 的推送不行，希望能解决我这个问题，感谢，thanks

Is there a way for the app currently playing music or voice in the background to know when a Critical Alert or push comes? Currently, my app contains code that stops playback when a call comes in while music or voice is playing in the background. So, if a call comes in during playback, it stops normally. However, there is a phenomenon in which playback cannot be stopped when a Critical Alert or push comes. When a Critical Alert or push comes to the device, is there a way in the code for the app currently playing music or voice in the background or foreground to know at that moment? We are not sending out Critical Alerts or pushes. I would like to know how to resolve the situation when receiving a Critical Alert or push sent to all users in one country.

Some customers could not receive the push notification, is there any services down?

I'm facing an issue where I can't play an audio file stored in my project after receiving a push-to-talk notification. Strangely, I'm able to play the audio file by tapping on a button before receiving the push notification, but it doesn't work afterward without any error messages. I've ensured that I've set up everything correctly in my project's capabilities. Any insights on what might be causing this issue would be greatly appreciated. I set everything in capabilities Set permission in .plist Request permission in app delegate I make connection to the room when app becomes active and received succes Then I setup .halfDuplex for this channel In restoredChannelUUID I activate AVAudioSession After sending the ppt push, I parse speaker and make it activeRemoteParticipant. I see than delegate function channelManager didActivate works good Where I tried to play audio from my player I see this prints in console, but no sound play

大家好，我正在尝试制作一个关于如何检测手机屏幕前是否有物体的演示。如果有物体，屏幕将显示红色，如果没有物体，则显示绿色。这可能需要调用距离传感器，但我不知道如何调用它。希望大家能给我一个回应。谢谢。

background I want to know whether an installed app has added the "Removable" option that value is true reference We used InstallApplicationCommand with the Removable option to install the app to a managed device. https://developer.apple.com/documentation/devicemanagement/installapplicationcommand/command/attributes?language=objc Question matters I checked the following items, but no items could be obtained. https://developer.apple.com/documentation/devicemanagement/installedapplicationlistresponse?language=objc https://developer.apple.com/documentation/devicemanagement/installedapplicationlistresponse/installedapplicationlistitem?language=objc Is there any other way to determine whether an app installed on a device is removable?

I had post my app after a long develpment period, I don't know why. but in some devices works well, but in others is difficult to notice what is going on. First: my app is a softphone voip, but keep app open or in background for our register be active is not effective because of battery safety. Then is when apns coming in, we just need that or app come back to be active, even in background, to our call shows up. and this happens well in our development enviroment, exacly like I describe. but in some devices doesn't work at all. We are using apns and firebase tokens to identify our registers and devices, and keeping together in our server/DB. I will share a image to explain better the flux that I implemented: Yes, I followed all instructions to insert apns, p12 and p8 certifies in the project, I just don't know why is working only in some devices. If anybody try test this function in my app, doesn't will work because I put some rules about IP address.

My goal is to send an image via APNS and let the user store it in the Photos app or the Files app. Does APNS support this functionality? How can I test it?

hello I'd like to transfer my application to another Apple dev account in the near future, my application uses FireBase cloud messaging to receive notifications What exactly should I do once the transfer is done? Should I just update the APNs authentication key on the FireBase console in Project parameters ? Should I also change the team ID on the fireBase console ? Does this mean generating a new GoogleService-Info.plist file and therefore an application update ?

Our MDM customers often claim MDM push is not delivered to device and cannot manage devices via MDM. The user first uninstalled the old description file and then installed the new one, but after the new description file was installed, our mdm server did not receive any notification from Apple about updating the token, only received an Authenticate message We tried to restore network settings but it did not work. We hope to get your help to solve this problem. Currently, we can't figure out where the problem is.
