Apple TV app is too limited – YouTube: Watch, Listen, Stream Review
The youtube app for Apple TV 4 is for passive viewing only. Any user interaction requires the website or iOS app. On the aTV
Users can: watch videos; watch subscriptions, search videos.
Users cannot: see description, rate videos (thumbs up/down), (un)subscribe to channel, add videos to playlist, read comments, or even see other videos by uploader (unless you are subscribed to their channel).
It's disappointing that the app for the Apple TV 4 is neutered of many features that were available on the retired app of the old aTV 2 and 3.
If you want to know what you are watching and by whom, curate a collection of videos, or even just rate videos, then you'd be better off using your iPhone or iPad with Airplay to send a video to Apple TV.
