Hi, I’ve read through your report, and based on the information you’ve provided, this looks like a possible App Store Connect submission-state synchronization issue rather than a problem with your app itself. Since you’ve already tried cancelling through both the App Store Connect interface and an authenticated request, and received HTTP 409 (STATE_ERROR.ENTITY_STATE_INVALID), I would suggest the following: Verify the account permissions. Make sure you’re signed in as the Account Holder, Admin, or App Manager, as Apple requires one of these roles to remove a submission from review. Check both official cancellation options. In App Store Connect, open App Review → Submissions and try “Cancel Submission”. Alternatively, open the affected app version and select “Remove this version from review”, if available. Escalate through Apple Developer Support. If both options fail, as your previous testing suggests, contact Apple Developer Support and explicitly request escalation to the App Store Connect engineering team. Include the HTTP 409 error, submission ID, app ID, affected statuses, and timestamps. Request a server-side investigation. Ask Apple to verify whether the submission is actually progressing through App Review or is blocked by an inconsistent backend state. If necessary, request that Apple correct the state or safely cancel the submission on their side. Keep the existing support case open. Reference your previous support conversations and the accepted expedited-review request so that Apple can connect the information to the same submission. I would avoid repeatedly cancelling, resubmitting, or using undocumented internal endpoints until Apple confirms the submission’s actual state. Apple’s official documentation confirms that submissions can normally be cancelled during review, so a persistent state-related error deserves further investigation.
