@DTS Engineer Case IDs: （20000121792563、20000118834823） Apple DTS Technical Support ID: 21268458

@DTS Engineer Our macOS apps pass full Apple code signature verification, yet every notarization submission remains stuck in the In Progress queue indefinitely with no resolution, failure logs, or completion notifications. Issue Timeline & Key Details (Beijing Time) Start of failure window: 10:40, July 25, 2026 (We once encountered task backlog issues before this incident, but those tasks would resume and finish within several hours automatically) All notarization jobs submitted after this timestamp remain in the "In Progress" status permanently Data cutoff for pending tasks: 14:05, July 28, 2026 Total pending tasks: 60 The oldest pending submission has been unprocessed for over 87 hours Baseline context: Our team had no notarization queue or processing issues before July 25; app signature validation always succeeds locally Core Questions We Need Official Answers To Are there any account freezes, pending reviews, service restrictions or incorrect backend configurations on our developer team account that affect notarization processing? What actionable steps can our engineering team take to resume normal notarization processing? What are the official methods to cancel long-pending notarization tasks via Apple’s notary backend console? Does Apple’s notarization service process all submissions under one developer Team ID in a serial queue? This issue has delayed our product release progress. We kindly ask for resolution steps at your earliest convenience. Thanks,
