I synced my iPhone 7 with my iMac. In the music app it is saying track unavailable. I have owned these tracks for years. They are from my own cd collection and apple won't let me play them ! They are greyed out. Image attached
No ia am not subscribed to Apple Music. It's my cd. The album is space oddity by David Bowie. I own the album. Only a few tracks from the album will play but the whole album is loaded on my phone.
I tried a re-sync, same thing, some tracks were greyed out and some would play. Then I went back into the music menu and selected 'Downloaded' and it was showing 'tracks downloaded onto this iPhone'. I then went back to play from this menu and all 10 tracks on the album worked. When I go back into the normal menu only 5 of them work, very strange.
I don't subscribe to apple music, only use my own downloaded music on that app. I use spotify for my subscription as it does not mess with my library as much.
So I guess it's fixed kind of, or its a work around for the moment. Hving a few issues with itunes on Sierra too, since the upgrade much of my movie cover art has disappeared (again, movies I own).
