What's the Cloud icon mean?
I have a number of playlists, built from music imported from my old CD library. Some of the tracks end up with this dotted cloud icon, and whenever I try to share these playlists on Apple Music, those tracks are omitted from my shared playlists.
What exactly does that icon mean, and how do I address it so that my complete playlist gets shared on Apple Music?
