TestFlight builds appear but cannot be installed – "The requested app is not available or doesn't exist"

Hello,

I am experiencing an issue that affects every app under my Apple Developer account, and after extensive troubleshooting I believe this is an Apple-side backend issue.

Developer Team ID: V94M8SUV94

Issue

Every TestFlight build uploads and processes successfully.

The build status becomes "Testing", internal testers receive the invitation, and the app appears correctly in TestFlight with:

App icon App name Version Description Install button

However, as soon as Install is tapped (within 1–2 seconds), TestFlight displays:

The requested app is not available or doesn't exist."

This issue affects

  • Every app under my developer account
  • Every uploaded build
  • Every internal tester
  • Multiple Apple IDs
  • Multiple iPhones

Things I have already verified

  • Apple Developer Program membership is Active
  • Free Apps Agreement is Active
  • Paid Apps Agreement is Active
  • Banking information is Active
  • Tax forms (W-8BEN and Certificate of Foreign Status) are Active
  • App Availability is enabled in 175 countries/regions
  • No countries are in Processing
  • Distribution certificates are valid
  • Builds finish processing successfully
  • Builds show Testing
  • Internal TestFlight groups are configured correctly
  • Multiple new builds have been uploaded
  • Multiple devices have been tested

Important observation

The same Apple IDs and devices can successfully install TestFlight apps from other developers.

Only apps from my developer account fail to install.

Support cases

I currently have two open Apple Developer Support cases:

  • Case ID: 102931480856
  • Case ID: 102933805150

Unfortunately, I have not yet received a resolution.

Apple Developer Forum

I found several forum threads where other developers reported the exact same behavior. Some later reported that Apple resolved the issue through backend intervention without requiring changes to the app or App Store Connect configuration.

Has anyone experienced this recently?

If an Apple engineer sees this, could you please verify whether Developer Team ID V94M8SUV94 is affected by a known TestFlight backend issue or requires backend reprovisioning?

As far as my research the issue is in beta app agrement Any guidance would be greatly appreciated, as this is currently blocking all internal testing for my clients.

Thank you.

Can anyone help?
