Still broken as of 12 Sep 2026, and it now affects two apps on my team.
Builds show VALID / IN_BETA_TESTING in App Store Connect and are assigned to an internal group, but installing fails with "The requested app is not available or doesn't exist". The install request returns 404 with failureReason "Error Downloading Install Data" and percentComplete 0 — nothing downloads. Same on iPhone (iOS 27.0) and on an Apple silicon Mac.
One detail that may help narrow it down: on 22 Aug I removed one app record, and at that exact second (2026-08-22 06:19:18 UTC-7) eleven builds expired — all eight builds of the app I removed, and all three builds of a different app that I did not remove, which happened to share the same version and build numbers. Every build uploaded since then fails to install. Restoring the removed app did not help, and a fresh build uploaded to the restored app also fails.
Nothing developer-side has changed the outcome: new builds, a new version string, new internal groups with both automatic and manual distribution, re-adding testers, and deleting a duplicate betaTester record (DELETE returns 204 and the record comes back with the same id).
FB24751999 (filed 12 Sep, with sysdiagnose). Developer Support case 20000147725637 is open.
