Filed as FB24607357 (Team ID JPL3AZ6T39).

Our team is affected as well. Team ID: JPL3AZ6T39 Bundle ID: com.volkankiyici.formpano (Sign in with Apple enabled, PRIMARY_APP_CONSENT verified via App Store Connect API) App: Wealthen (App Store id 6797299929, live version 1.2) Identical signature to this thread: the sheet authenticates successfully (Face ID OK), then shows "Sign-Up Not Completed"; ASAuthorizationController fails and no authorization request ever reaches our backend (server logs confirm all other app traffic arriving normally). Reproduced on a physical iPhone (iOS 26) with TestFlight build 1.3 (108); App Review hit the same on iPhone 17 Pro Max / iOS 26.6 and rejected our submission (2.1a). Sign-in with the identical code worked until Aug 31, 21:48 (UTC+3); failures began Sep 1, shortly after an automatic-signing provisioning refresh. Entitlements verified inside the distribution-signed binary and embedded profile; capability re-saved via ASC API with no effect, consistent with earlier reports here. Could this team please be checked/repaired server-side like the earlier teams in this thread? Happy to provide sysdiagnose/akd logs and a Feedback ID if useful.
