You may have noticed that on January 1st the Do Not Disturb feature on your iPhone stopped working. Rather than turning itself off automatically, on January 1st many users found out that the Do Not Disturb feature stayed on and they didn’t get any notifications.
Apple’s aware of the issue and they’ve already released some information on the bug, saying that it will be fixed on January 7th.
On their Support website, Apple released the following info:
Do Not Disturb scheduling feature will resume normal functionality after January 7, 2013. Before this date, you should manually turn the Do Not Disturb feature on or off.
To turn off the scheduling feature, tap Settings > Notifications > Do Not Disturb and switch Scheduled to Off.
Turning the feature off and on manually isn’t ideal, but at least the fix is coming in the next 5 days.
