The most recent changes made to YT app on tvOS is really, really awful, granted it looks very similar to all other mobile devices, however, it just sucks in the worst way possible. On top of the horrible interface, my history and watchlist is no longer linked with my other devices, and, yes, I am signed in to the same account. I just hate google more and more with stuff like this. I wish people would use Vimeo instead.
> However, AirPlay from my iOS devices works great, in fact, better than using the tvOS app, if I pause, I don't get bombarded with all kinds of stuff all over the screen, I just get the usual bar at bottom.
But, I don't think the YouTube app should be the factor for what streaming device you get, not by any means. (Unless you pay for YouTube, I guess.)
