So I have just checked the "available offline" option on for all of my songs. Nearly all of them have synced to my phone, but around 300 still won't download. Also, whenver I play any song, no artwork shows whatsoever. If I uncheck "available offline" then the artwork reappears.
Also, artwork for local songs will not show or sync either.
Why is this happening, and how can I fix it?
