Changing the default alarm sound only affects new alarms created after changing the sound. You need to edit the existing alarms individually to change their alarm sounds.
How do you find the existing alarms and change the sounds there? I actually can't find it.
Anyway, my celebrity alarm sound actually just worked today. I set up alarm for 8pm. It was 6pm I think when I set it up. And bam the celebrity alarm is the sound.
But when I try to alarm for a minute after that, then it's back to default sound.
Oh well. Also can you set up alarm sound using zedge app? I don't find any option for that.
I already called tech support. They are no help. They actually said the same thing. Unplug it then don't use it for awhile.
