Same issue, still not fixed as of 2026-10-07. Team ID: Z2MC535RQP Bundle ID: com.balbadak.app (App Store app 6797557359) Also reproduced with a brand-new minimal App ID: com.balbadak.siwatest (95-line UIKit project, no backend) Sign in with Apple capability enabled: 2026-08-14 (Primary App Consent) Symptom: system sheet appears → "Sign Up Not Completed" → ASAuthorizationError 1001 (empty userInfo) akd: "Encountered error while fetching developer team: AKSQLError -6003" → "No applications were found with the provided Client ID" → "M2 missing" → AKAuthenticationServerError -24000 What we tried today (2026-10-07), all still failing: Regenerated the App Store provisioning profile (same cert), new TestFlight build 1.2.4 (27) → same "Sign Up Not Completed" Created a Services ID (com.balbadak.web) + new SIWA key for the web flow → appleid.apple.com shows our app name/icon, but sign-in fails with "There was a problem. Try again." after entering the password Control test: same device, same Apple Account, an app from a different team (A2H9H48723) signs in successfully. Feedback: FB24687360 DTS Case-ID: 21791071 @Paris X Pinkney could you please apply the same server-side team registration fix to Z2MC535RQP? We have been unable to ship Sign in with Apple since August. Thank you.
