It looks like Apple's convenient overnight update feature is causing more problems than expected. AppleInsider reports that a bug in iOS 9.1 shuts off their alarms while users were sleeping. As a result, users who needed to get up in the morning found themselves still in bed and late for their morning engagements.
Several took to Twitter to express their dismay, like Pixies lead guitarist Joey Santiago:
All of our iPhones alarms failed to wake up our household. Did anyone's iPhone alarm go off this morning?— Joey Santiago (@JoeySantiago) October 28, 2015
Apple hasn't yet responded to the issue, but for now users can be content to know that the problem only comes with the update and alarms will work just fine as soon as 9.1 is installed. Hopefully subsequent updates won't have the problem. Still, this isn't at all the first time iOS has had alarm-related issues. Back in 2010, a Daylight Savings Time issue caused alarms to malfunction. More recently, iOS 9.0.1 was released in part to patch a bug that prevented alarms from going off.
