I just upgraded my iPhone and found out on a plane that my music is apparently only syncing via cloud library but is not actually downloaded to my device. Got on the plane and all my music was greyed out, none of it available offline. I don’t actually have Apple Music, I just have music I’ve purchased from the iTunes stores and also downloaded to my MacBook from other sources. I know you can hit the three dots on a playlist and select download but I want to do all my music, including songs that aren’t in my curated playlists. How can I do this?
