app cannot be installed because it's integrity could not be verified

2nd day, same problem...Today morning (GMT +1) working fine for few hours, and than again same problem...I was able to update to the latest version on TestFlight without any problem. After that, same scenario again, "App cannot be installed..."

Still waiting for Apple to resolve issue, meanwhile my client that wanna test the changes that i made in the app's are angrier and angrier...

Do i need to mention that client = founding = money (in this case loosing the same) ???

Did anyone try to release the app and open it for the customers even if this issue is on TF? Does it affect the end-user after releasing the app?

I am having the same issue as well.

I too faced this issue today. Just got a temporary way to install the app successfully. The following steps worked for me:

1. Delete the old app from your iPhone.
2. Open TestFlight app on your iPhone/testing device and install the last successful build of your app from TestFlight which didn't cause this integrity issue.
3. Once old version of your app is successfully installed, then come to latest build of your app on TestFlight app and tap the 'Update' button.
4. Once successfully updated, now you will be able to open and run your app without any issue.

same to me :(

Seeing this too. Interestingly, on an iPhone 8 using iOS 14 the same build could install, repeatedly fine with no problems! on iOS 16 installs are all failing so far.

Same here. What's happening ?

Same problem for me. @Apple - help please

Hello @Apple Dev Team and everyone here. Experiencing the same issue starting from today Thu 8 Dec, 2022. To make things worse, using Xcode Version 13.2.1 (13C100) and an old iPhone (8 Plus), I cannot run and test on device but every works fine on Simulator. We are pretty sure you are doing your very best right now to fix and we appreciate.

We are also facing same issue. Dear Apple Team whats happening with TestFlight? But my app was successfully reviewed by Apple team and ready for release. If I released the app on AppStore my app users will also get this same message like this ? "app cannot be installed because it's integrity could not be verified".

 Apple Team please help on this

Same here with three different beta Apps, on different devices with IOS 15 and 16

fyi apple posted a response to another thread on this issue (see page 12 of this thread), they are working on it: https://developer.apple.com/forums/thread/701330?page=12

same for me

Good day my fellow Appler, it looks like there's an outage with the "Developer ID Notary Service", which can be seen here.. This is most likely the root of the issue you're (we're) having.
