TestFlight install fails: “The requested app is not available or doesn’t exist” (Internal testing)

Hi all,

We can’t install our app from TestFlight. The app is visible in TestFlight for invited internal testers, but tapping Install fails immediately with:

“The requested app is not available or doesn’t exist.”

--Setup--

Distribution: TestFlight – Internal Testing

Internal group created and testers added (invite accepted)

Build processing status in App Store Connect: Complete

TestFlight build status shows: Ready to Submit / Prepare for Submission

Minimum iOS deployment target: iOS 15.0

Version/Build: 1.0.0 (1)

What we tried

Confirmed tester is signed into TestFlight with the same Apple ID email that was invited

Removed/added testers to the internal group and resent invites

Reinstalled TestFlight, signed out/in

Verified build is assigned to the internal group

Set and saved Monetization → Pricing and Availability → App Availability (All Countries/Regions)

Question

Has anyone resolved this issue? Is there a known TestFlight/App Store Connect stuck state that causes this error even for internal testing? Any recommended steps (new build number, group reset, availability/pricing settings, etc.)?

Screenshots available (TestFlight error + App Store Connect build/group view).

Thanks.
