Unable to install any TestFlight apps for several days. Could this be an Apple Developer account issue?

Hi everyone,

I'm wondering if anyone else is experiencing the same issue.

For the past several days, I have been completely unable to install any of my TestFlight applications. The problem affects every app on my Apple Developer account, not just a single project.

Here is what I've verified so far:

  • Builds upload successfully.
  • App Store Connect finishes processing without errors.
  • The builds appear in TestFlight.
  • My certificates and provisioning profiles appear to be valid.
  • I have tested on different networks and users.
  • The issue still persists.

The installation simply fails, making it impossible to test my applications.

I have already contacted Apple Support but have not yet received a response. At this point, I'm starting to wonder whether there could be an issue with my Apple Developer account or a backend problem affecting TestFlight.

Has anyone experienced something similar recently?

If you have, did Apple identify the cause or provide a solution?

Any information would be greatly appreciated.

My Mac Catalyst apps aren't showing up in TestFlight (macOS) anymore since July 15. iOS builds ARE showing up though. The status on AppStoreConnect indicates no issues with the apps that don't show up.

I had a similar TestFlight issue in July (builds processed fine but wouldn't install — affected my whole account). Feedback Assistant was useless, only automated replies. What fixed it: I opened a case directly with Apple Developer Support (developer.apple.com/contact). A senior advisor confirmed it was an account-level backend issue on Apple's side, they 'took action' on July 15, and told me to wait 48h and upload a NEW build — after that everything worked.

Since your problem started exactly around July 15 and App Store Connect shows no errors, I'd bet it's related to backend changes Apple made then. Open a Developer Support case (not Feedback Assistant), mention it affects all your Mac Catalyst builds since July 15 while iOS works fine, and ask them to check your account/TestFlight config on their side. Also try uploading a fresh Catalyst build after contacting them — in my case old builds stayed broken, only new ones worked.

Yes Same Issue ! Opened ticket still no answer from Apple - Tried everything Modified Certificates

Even got Ai Involved to check all settings, everything checks out -
