@YouTubeTV are improvements coming to the Apple Tv app? Trying to skip back or forward a few seconds (something that's super slick and easy in your iOS app) is just impossible on Apple TV.
It's not the functionality. It's the UX to rewind/fast forward. It's unusable on Apple TV. There's no support for the 10-sec skip forward or backwards, and the seek via thumb left or thumb right (on remote) doesn't work well because it snaps to the currently selected time.
