Apple Devices can't see my playlists
I'm PC-based. I keep all my music on my PC, in mp3 format, and sync it to my phone via iTunes - til now. Music has been kicked out of iTunes as of Saturday morning - apparently there's some cutoff date that has been reached without me receiving a single notification, despite being a daily user of iTunes on my computer.
I have installed Apple Music and Apple Devices apps on my machine, which apparently replace (somewhat) trusty ol' iTunes. When I synced my phone, all my music disappeared. Apparently my playlists, while intact on Apple Music, can't be seen by Apple Devices. All the Artists, Albums, Genres are there in AD but nothing under Playlists! Help!
There is some material on the web about a "Sync Library" function, but when I follow instructions to update that setting, the setting doesn't exist where they say it is, nor anywhere I can find so far.
But I think there is some issue with Apple Devices? I'm not sure what to do now. Is there some way to connect the playlists to Apple Devices?
