Users of my app have reported that they are sometimes unable to receive Voice-over-IP (VoIP) push notifications when using a SIM.

Managing notifications and extension expiring certificates
Hi everyoneI I’m maintining an app that uses the Notification Service Extension entitlement (which I have never used before). The app is not published on the App Store but is delivered OTA via a website. previous developer told me that to avoid certificate expiration issues, they started using the APNs Auth Key on the server in the past. However, I now have two certificates close to expiration on the developer profile page. Both certificates are of the type "Apple Push Services": The first one is named with my app's bundle ID (MyInstitution.AppName). The second is named after the Notification Service Extension entitlement (MyInstitution.AppName.NotificationServiceExtension). In the Key section on the developer profile page, under Certificates, Identifiers & Profiles -> Keys section, there is a key named "MyInstitution NSE." My questions are: What should I do with the expiring certificates now that the app is using the APNs Auth Key? Is the Notification Service Extension entitlement working separately from the APNs Auth Key? In the end, does something really need to be renewed? What needs to be renewed, and how? When should I perform this operation if needed? Do I need to create a new .ipa file and distribute it? I have added some screenshots to be clearer (names hidden for privacy concerns):

Custom Push Notifications for Apple Wallet Pass Not Received
Hello everyone, I'm having trouble with sending custom push notifications for Apple Wallet passes. Here's what I've done so far: Registered a new pass: I receive a deviceToken for the pass. Enabled Push Notifications: Push notifications for the Apple Wallet app and the specific pass are enabled on my phone. Added the Key for Push Notifications: I've added the necessary key for push notifications. I use following code to send the message via APNS: const tokenKey = fs.readFileSync(options.tokenPath).toString(); jwtToken = sign({}, tokenKey, { algorithm: 'ES256', expiresIn: '1h', issuer: options.teamId, header: { alg: 'ES256', kid: options.keyId } }); const client = http2.connect('https://api.push.apple.com:443'); const notificationPayload = JSON.stringify({ aps: { "alert" : "Hello" } }); // and try //{ // "aps": { // "alert": "Your pass has been updated!", // "sound": "default" // }, // "pass-type-identifier": "pass.com.example.myPass", // "serial-number": "123456789", // "device-token": "<deviceToken>" //} const request = client.request({ ':method': 'POST', ':path': `/3/device/${deviceToken}`, 'apns-topic': topicId, 'apns-push-type': 'alert', 'authorization': `bearer ${jwtToken}`, 'apns-priority': 10, 'content-type': 'application/json', 'content-length': Buffer.byteLength(notificationPayload) }); return new Promise((resolve, reject) => { request.on('response', (headers, flags) => { for (const name in headers) { console.log(`${name}: ${headers[name]}`); } }); request.on('data', (chunk: string) => console.log(chunk)); request.on('end', () => { client.close(); resolve(); }); request.on('error', (err) => { console.error('Error sending push notification:', err); reject(err); }); request.write(notificationPayload); request.end(); }); When I send the message, I receive a :status:200 and a apns-ID, indicating that the message has been sent. However, I do not receive the custom push notifications on my phone. The pass updates are received without any issues, but the notifications are not. Has anyone encountered this issue or know if it's possible to send custom push notifications for Apple Wallet passes in this manner? Any guidance on how to resolve this issue would be greatly appreciated.

Push notifications are not displaying when app is in foreground
I have some C++ code to embed in my Application and hence enabling the setting C++ and Objective C ++ compatibility settings to C++/objective-C++ under build settings of my project .Once I enable it I am not receiving any push notification display when I'm in foreground even though I have the required willPresent function handler in app delegate. Also observed that the code is going into didReceiveRemoteNotification function handler. But once I disable the setting or change the setting to c/objective-c,then the flow is working fine and I'm getting the push notification on foreground. Request you to please help me here

iOS dosen't call didActivateAudioSession
PLATFORM AND VERSION iOS Development environment: Xcode 15.0, macOS 14.4.1, Objective-C Run-time configuration: iOS 17.2.1, DESCRIPTION OF PROBLEM I am developing an application that uses NetworkExtension (VoIP local push function). But iOS sometimes doesn't call didActivateAudioSession after following sequence. Would you tell me why iOS doesn't call didActivateAudioSession ? (I said "sometimes", but once it occurs, it will occur repeatedly) myApp --- CXStartCallAction --->iOS myApp <-- performStartCallAction callback --- iOS myApp --- AVAudioSession setCategory: AVAudioSessionCategoryPlayAndRecord --->iOS myApp --- AVAudioSession setMode: AVAudioSessionModeVoiceChat --->iOS myApp <-- didActivateAudioSession callback ----iOS I suspect that myApp cannot acquire an AVAudioSession if another app is already using AVAudioSession. [QUESTION1] Is my guess correct? Should I consider another cause? [QUESTION2] If my guess is correct, how can I prove if another app is already using an AVAudioSession? This issue is based on a customer complaint, but the customer said they don't use any other apps. Best Regards,

iOS Push to Talk Framework Not Working in Archive Build (Flutter)
I have developed an app using Flutter that utilizes the Push to Talk framework on iOS. The Push to Talk feature works perfectly in debug mode, but after archiving the build and installing it on an iOS 17 device, the Push to Talk functionality stops working. Here are the steps I have already taken: Enabled background modes. Enabled Push to Talk capabilities. Despite these settings, the issue persists in the archive build. Has anyone else encountered this issue? What additional steps or configurations are required to get Push to Talk working in the archive build on iOS 17? Any help or guidance would be greatly appreciated. Thank you!

Silent push notification denied: pushDisallowed
Hi We are using silent push notifications in our app, these trigger our app to run code that syncs data with our server. This includes time sensitive data which the user will want to know about (which we send alerts generated on the device for). We know we are probably not using the notifications system as intended, we plan to rectify this soon using alert push notifications. To begin, we were willing to run the risk of sometimes having our code not be able to run in background, in exchange for less code complexity. However we did not expect it to be this unreliable. The app is functionally never allowed to promptly run our sync code. We believe the likelihood of promptly being able to run code has also declined significantly in the last few months. It used to perform better. There are of course many reasons that the app may be denied being able to run, battery, wifi / data, cpu. But when any of these are the reason these provide transparent rationale. The most common rationale we see is Rationale: [{[pushDisallowed]: Required:0.00, Observed:1.00}, TLDR "pushDisallowed" is a very opaque rationale, we were hoping to have some insight as what makes up the "pushDisallowed" reasoning. Presumably there are many factors that go into this, a rough list would be very helpful. We aren't necessarily seeking an answer for why our app is being denied, but why apps in general are denied with this rationale. We cannot find anything in the documentation outlining this. Full example console message default 16:16:12.710320+1200 dasd com.apple.pushLaunch.nz.co.appName.ios:7808B2:[ {name: ApplicationPolicy, policyWeight: 50.000, response: {Decision: Absolutely Must Not Proceed, Score: 0.00, Rationale: [{[pushDisallowed]: Required:0.00, Observed:1.00},]}}

Push Notification User to User
Hello everyone, I'm getting desperate... I have built a small chat app and just can't get the other person to receive a push notification outside the app. Does anyone have a code snippet or an idea how I can solve this? I'm getting desperate! I have already tried a lot, the best would be a local solution where the message is triggered when the user receives a new message. I would be happy to receive code snippets or tips. Sending via OneSignal works, but as I said, I just can't get the user to user messages to work!

Potential Apple Pay Notification Delay in iOS 18 Developer Beta
Potential Apple Pay Notification Delay in iOS 18 Developer Beta Users are reporting a delay in receiving purchase notifications in Apple Wallet after using Apple Pay. Transactions are confirmed within the Wallet app, but the notification arrives hours later. As this issue is occurring on the iOS 18 developer beta, it's likely a software bug related to Apple Pay integration with Wallet. I have reported this to Feedback. Is anyone else having the same problem?
