We are still reproducing the same failure on MeetRackets. Team ID: QWH2C4XE3J Primary App ID: com.frantor.meetrackets (resource ID 486P895R59) Services ID: com.frantor.meetrackets.web (resource ID Q6SZ3ZC4V3) Feedback Assistant: FB24225167 This is the Sign in with Apple JS/PWA flow from https://dev.meetrackets.com. The Apple consent UI loads and recognizes MeetRackets Web, but the final submit fails inside appleid.apple.com before our callback is reached. Desktop DevTools shows Apple-internal authorization requests returning HTTP 409 followed by HTTP 403. We reproduced it with two independent Apple Accounts on different physical iOS devices, including a first-time signup. Our DEV backend and database receive no authorization code, identity token, or Apple identity. The Services ID, primary association, domains, exact return URL, APPLE_ID_AUTH / PRIMARY_APP_CONSENT, TLS, and request parameters have been rechecked. Could Apple please inspect and re-provision the server-side Sign in with Apple registration for this Team/App ID/Services ID?
