So today is the 4th time that my entire library of music was deleted off of my phone. The previous times were mainly from accidents on my part such as accidentally signing out of my Apple ID and what not, but this time I literally have no clue why... I know my library was on here when I got in the car half an hour ago because the screen lit up with my first song as it always does when it connects to Bluetooth. However, I opened my music app 20 minutes later and lone and behold, all my music is gone. I did not touch my Apple ID or anything. The only thing I did was turn off my cellular data at one point because my data plan is about to go over, but I've since turned it on and I don't believe that has anything to do with it at all? All I know is I opened my music app and there was the dreaded "Don't Miss a Beat" screen... Any suggestions? Thanks!
