Artwork not updating
I have albums with iTunes match with their own artwork (For example, singles) and I combine them all together to make one album with one artwork (For example, a full length album containing the singles) and at first they all have this new artwork but after a while the old artwork is back on the original files.
I have tried various troubleshooting techniques on my own but nothing has worked. I have went into each individual song and deleted the artwork and added the new artwork separately, nothing seems to work.
Can someone help me with my problem?
