I have 3 alarms set up for various times of the day. Like my wakeup alarm is setup to 7:30 a.m. weekday mornings. I have the alarm sound as a music ringtone file, and I have it also set to vibrate. I did not hear my alarm sound off at all, and was not in a deep sleep. Has anyone else had a problem with their alarms not sounding? I didn't try it with a sound file instead of a music file, but that shouldn't matter I'm thinking. Any suggestions for a fix or for another alarm app that does work for sure? Thanks for your help.
