So I sent this to apple (in a feedback form). Does anyone have the same issue??
"If I download an album/song/playlist that I had before Apple music, it won't play if I don't have a connection. Even though it is downloaded! When I play it with a connection it works fine and doesn't waste my data.
So for some reason I need a connection to play those songs but it doesn't download them again or stream them. Please could you fix this as if I go on a plane etc. I'll only be able to listen to music that I've added to my library from apple music. Thanks"
