The new year has started. Many iOS users woke up late, much to their surprise, because the alarm did not work.
This happened last year on the 1st January or 2nd January when many iOS users were afflicted by a bug that prevented their set alarms from actually working. Due to this bug, problems were apparent for the users who had to go to work or catch flights. The bug affected single-use alarms set on the January 1st and 2nd. Alarms that were scheduled to repeat at least once throughout the week were not affected.
