Apple Music/Sync Library was fine now it's wiped all playlists on phone
Just converted to Apple Music with sync library. Cleaned up, things stable. Now today all the playlists have been wiped on my phone except "Purchased Music". they are intact on my Mac. What gives.
The only thing different I have done recently, besides prematurely sing the praises of Apple Music in this forum, is plug my phone into my Mac to sort out some photos. Music tab in Finder states that it's not going to apply sync because I am using Sync Library, though the little update wheel next to my phone in finder did spin so it was doing something, who knows what.
How do I force Apple Music to sync the playlists back into existence on my phone.
