Apple TV Top Shelf artwork missing
I have an Apple TV 4th generation with tvOS 9.2. I have the Computers app on the top row because I share all my media using iTunes and when I add content like movies, the recents are displayed in the Top Shelf of the Apple TV home screen. However, I've noticed that sometimes the artwork is missing. For example, I purchased It's the Easter Beagle, Charlie Brown from iTunes and it's artwork is not displayed on the Top Shelf. Meanwhile, I also purchased Be my Valentine, Charlie Brown and it's artwork is displayed properly. Sometimes, this problem will go away if I add duplicate artwork to the file. In this case, it does not. The artwork is displayed properly if I open the Computers app and browse to the file. The artwork is also displayed properly with iTunes on my iMac. Does anyone know how to fix artwork that is not displayed in the Top Shelf of Apple TV?
