Our AppleTV started to lose it’s app icons. Some of them were grayed out. As if they were updating. It also said “waiting für update”. Our system was set up to update automatically and so we tried everything to rectify this annoying feature.
I went into the system setting of the Apple TV and went into manual software update and all of a sudden the tvOS 11 was able to be updated and that finally fixed the issue with the grayed out icons.
