I am running iOS 8.1 on my iPhone 6 Plus and I have a number of alarm clocks set up on it to go off throughout the day. Very recently I noticed that the alarms that I have set up for the morning don't go off. I triple checked all of the settings, and they should be working. I've also turned the Ringer Volume up all the way, and still nothing. When I finally wake up and check my iPhone, there is no message that an alarm had ever gone off. However, once I hit the sleep/wake button, and begin using my iPhone, the alarms that I have set later in the day seem to go off as scheduled. Anyone else having issues with the iPhone alarm clock?
