I am unable to submit any app for review. Every attempt to add a build to an App Store version results in a 409 error, both through the App Store Connect website and directly through the App Store Connect REST API. Affected accounts: Account 1: My personal Apple Developer account Account 2: A company-owned Apple Developer account where I have Admin access Both accounts are completely separate — different legal entities, different enrollments — but exhibit the exact same behavior simultaneously. API errors observed When calling PATCH /v1/appStoreVersions/{id}/relationships/build: 409 ENTITY_ERROR.RELATIONSHIP.INVALID "The specified pre-release build could not be added." When calling POST /v1/appStoreVersions to create a new version: 409 ENTITY_ERROR.RELATIONSHIP.INVALID "You cannot create a new version of the App in the current state." What I have verified All builds are processingState: VALID and not expired usesNonExemptEncryption: false is set on all builds No build is already attached to another version Build version string matches the App Store version (1.1.0) App bundle ID matches the build bundle ID Localization, review contact details, and keywords are all filled in Banking info in Agreements, Tax, and Banking was recently updated on both accounts Issue persists on both the website and via the REST API, ruling out a browser/cache issue Question Has anyone seen 409 errors affecting two completely separate developer accounts simultaneously? Could there be a platform-level issue with App Store Connect that is not reflected on the System Status page? I opened a support ticket 1 week ago but I only got a reply today and it's just asking for more details.
