TestFlight: "The requested app is not available or doesn't exist" for all internal testers + 422 on Beta App Review submission

Hi,

Since October 24, 2026, TestFlight has been unusable for all three apps in our account (EmlakBase Pro, EmlakBase, BirSitem).

Developer Support case: 103007291888 (opened October 24, 2026; follow-ups sent October 29 and November 8). I haven't received a reply yet, and phone support has been unavailable whenever I tried (November 9 and 10).

1) Internal testing

Every internal tester sees the app in TestFlight, but tapping "Install" fails immediately with "The requested app is not available or doesn't exist." This also happens for a tester with the Admin role who accepted the invitation. New builds uploaded on November 6 show "Testing" in the internal group, yet no tester can install them.

2) External testing

Submitting a build to Beta App Review always fails with "There was an error processing your request. Please try again later." The request (POST /iris/v1/betaAppReviewSubmissions) returns 422 ENTITY_UNPROCESSABLE. The build is VALID, export compliance is set, its external state is READY_FOR_BETA_SUBMISSION, and the test information, review contact and demo account are complete.

What I've already checked or changed

  • Membership is active. I accepted the latest Program License Agreement and the Free Apps Agreement.
  • Certificates and provisioning profiles are valid, and builds process successfully.
  • Testers have the App Manager or Admin role, and their Apple Accounts match their invitations.
  • App availability is set to all countries or regions.
  • I cancelled an old App Store submission that was still open (Guideline 2.1, Information Needed). The 422 error continues.

Since this affects every tester across three separate apps, it looks like an issue with our account or app records on Apple's side. Could someone from Apple look into case 103007291888 or escalate it to the TestFlight team?

Thank you.
