The incident affected alerts for apps with auto-translation enabled only. The root cause was a mismatch between how checksums were calculated and stored for duplicate detection, which caused some alerts to be sent multiple times. This edge case was not covered in pre-release testing. The issue has been identified and addressed.
Missed reviews for today have been successfully triggered for the period during which alerts were paused.
Scheduling is planned to be enabled soon.
