Can't download music on newly setup device
I just setup a used iPad for my personal use. It used to belong to a family member. I logged out of their AppleID and into mine. Most things are working properly (mail, messages, photos, etc). However, the Music app is giving me some problems. It has sync'd my library and I can play music from my library, but I can't download any music. I get the following dialog:
I'm not even sure what "Transfer" means, or what this messages is all about. I don't subscribe to iTunes Match, and didn't even know what it was until I got this dialog and looked it up.
Another related issue (and what I actually noticed first) is in Settings -> Music, if I try to enable "Automatic Downloads", it simply turns back off if I touch any other setting, or leave the Music settings and then come back. I had been trying to fix this issue for a while when I finally decided to just try to manually download some songs in Music, and ran into the above dialog.
