Why is the artwork for my albums not syncing properly?
I was wondering if anyone else is having a problem with syncing their albums and the artwork that comes along with them? This problem started happening to me recently after I got an unknown error that would occasionally pop up when trying to sync my iPhone 5s (iOS 8.4.1) to iTunes (12.2.2). It would say and still says: "The iPhone "XV" cannot be synced. An unknown error occured (-54)." And yet it still syncs? But the problem comes with the syncing. Whenever I try to put new music on my iPhone, the artwork doesn't sync properly? It shows up just fine in iTunes, but when synced to my iPhone, it shows something completely different..Is there any way as to how I could go about fixing this problem? And could the problem be related to the unknown error?
