I was hoping Windows10 would also solve the fact that a lot of albums don't have cover art while there's cover art on the Windows Media Players of my Windows PC.
Does that really solve the problem ? Even if it does, it still makes no sense that a sync between pc and phone doesn't always sync the album cover art.
If I ripped the cd again en matched the album info with the Windows Media Player, than it worked using OneDrive. The old music files kept not showing artwork, even when using OneDrive.
