iPhone 12 Pro Max won't sync with iTunes
Recently bought a 12 Pro Max (512 GB). Restored it from my previously saved iPhone. However about half of the music playlists I am trying to put on the phone won't transfer. On iTunes I get the following pop-up:
This iPhone cannot be synced. The required file cannot be found.
However, the playlists do show up on my iPhone but are greyed out and when I try to play it, I get this message:
This song is not synced across your devices. On your Mac or PC, go to Apple Music or iTunes for Windows and in Preferences, select Sync Library.
I did select "Sync Library" at one point but it appeared that it was uploading my music to iCloud and I don't use iCloud and never have. So I stopped the sync.
Anyone have any suggestions?
