Not all album artwork showing on ipod touch (4th gen)?
A while back, I added some of my own artwork to some songs I downloaded to my library. At some point after that some of the album art disappeared when I was viewing the album list on my ipod (4th gen with iOS 6.1.6), and only then - artwork remained for songs and when looking in the album itself. The missing artwork seems to be at random although albums I recently bought (last few months) still have their artwork. I have restarted my ipod many times since the problem occurred, with no effect.
iPod touch, iOS 6.1.6, 4th gen
