The third generation Apple TV is going to be losing support for the dedicated YouTube app in March this year after being supported since 2013, over eight years. YouTube support for the older second generation was removed back in 2015 and going forward YouTube is suggesting that the newer Apple TV HD and Apple TV 4K are an option as well as AirPlay from an iPhone, iPod touch or iPhone to the third generation Apple TV.
The newer models run tvOS and have the App Store, with apps that share features with iOS apps and these two models run YouTube natively.
