Thanks, Chirag. Already tested this thoroughly: created a fresh Apple Distribution cert, regenerated the App Store profile tied to it, switched to Manual signing in Xcode explicitly selecting both, and verified via codesign that the build uses Apple Distribution (get-task-allow: false, no device list — genuine App Store signature). Still fails server-side with 90034. Opened a case with Apple Support (case 20000125779862), seems account-side.

Yes. I checked them. The Apple Developer account currently has valid certificates: Apple Development: valid until July 31, 2027 Apple Distribution: valid until August 1, 2027 Apple Distribution Managed: valid until August 1, 2027 The App Store provisioning profile is also Active and expires August 1, 2027. It is associated with the correct Bundle ID and Apple Distribution certificate. The issue still occurs, including with a brand-new Xcode project.
