All music deleted
I went to play my music and everything was gone, all my playists, etc. My iCloud music library is on and I’ve tried restarting my phone ,iPhone 7+, and nothing has worked. How do I get all of my playlists back?
Try these steps:
Get help with iCloud Music Library - Apple Support
If you can’t see iCloud Music Library on your iPhone, iPad, or iPod touch
First, restart your iOS device.
If you still can't see it after the restart:
1. Turn off iCloud Music Library and then turn it back on.
2. Sign out of the iTunes Store and then sign back in.
