maybe this could help


itunes shows this while sync. but the itunes library is empty!
all songs are sync by MM.

i'm using 4.1.7.1737 in portable mode

updated IOS 8.2 and itunes 12.1.1.4

with older versions i never saw this issue...

Hi, this issue has been fixed in 4.1.5.1718 :

Do you use 1718+ ??

If I sync my music to ipone by MM, all artworks are shown perfect on the iphone.
After running itunes to sync contacts and calendar all artworks are gone away!?

I tried disable itunes match. But problem is still there.
Does anyone have a solution for this issue?
