TestFlight Not Working – Internal Testers Can't Install & External Testing Fails

Hello,

I'm facing a TestFlight issue that started some time after renewing my Apple Developer Program membership.

Issue:

  • Builds upload and process successfully in App Store Connect.
  • Internal testers cannot install any build. TestFlight shows: "The requested app is not available or doesn't exist."
  • Submitting a build for external testing always fails with: "There was an error processing your request."

This is happening with every new build and has been occurring for over a last two week. The app had been distributed through TestFlight successfully before this issue started.
