iTunes won't sync with iPhone X
I bought a couple of albums from iTunes, and when I went to sync them to my iPhone X, all the songs wouldn't show up in the playlists. Sometimes only 3 songs showed up, sometimes none. I have iTunes 12.7.4.76 on my MacBook Pro mid-2010 -- is the computer too old? Does anyone know a solution to this?
iPhone X, iOS 12.1
