TestFlight installation fails with "The requested app is not available or doesn't exist"

Hi,

I'm unable to install my app through TestFlight.

When I tap Install, TestFlight immediately shows:

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

What I've verified:

  • Build upload succeeds.
  • Build processing completes successfully.
  • Build is assigned to my internal testing group.
  • Bundle ID is correct.
  • Same Apple ID is used for App Store Connect and TestFlight.
  • The app installs and runs correctly on the same iPhone when installed directly from Xcode.

I've already tried:

  • Uploading multiple new builds.
  • Removing and reinstalling TestFlight.
  • Restarting the device.

The issue only occurs when installing through TestFlight.

Has anyone experienced this recently? Is there anything else I should check?

Thanks!
