@Paris X Pinkney — same signature for another team, also hit by App Review (2.1(a) rejection, Oct 21). Team ID: M6HQZ4NFAY (Nyza Creations LLC) · App ID / client ID: ai.sikho.app (primary, APPLE_ID_AUTH = PRIMARY_APP_CONSENT) · Services ID: ai.sikho.web · Feedback: FB25205421 The native sheet renders, Face ID succeeds, then "Sign-Up Not Completed"; ASAuthorizationController returns 1001 and nothing reaches our backend. It is intermittent, which matches a server that lacks our registration: App Review's attempts on iOS/iPadOS 27.0 (2026-10-21 05:42–05:44 UTC) all failed, while other first-time sign-ups succeeded (Oct 12–20) and our own iPhone signed in three times today, including a fresh authorization after Stop Using (2026-10-22 18:31:53 UTC). The public authorize endpoint shows the split every time: at 2026-10-22 18:25 UTC, 17.157.64.68 returned "Invalid client." for ai.sikho.app and "No AppPlatform or Primary app for the web application" for ai.sikho.web (3/3 each), while 17.111.105.242, 17.23.96.16, 17.32.194.37 and 17.32.194.6 recognized both. Our other App IDs (e.g. ai.fashy.app) are recognized on all five, including 17.157.64.68. Same result daily since Oct 10. Verified: applesignin = ["Default"] and application-identifier M6HQZ4NFAY.ai.sikho.app in the signed binary and its ACTIVE App Store profile. An unchanged re-save on Oct 12 made no difference. Could the same server-side registration repair applied to the teams above be applied to ai.sikho.app and ai.sikho.web? We can re-test immediately and will close the Feedback once it works.
