Does not support 5.1 sound, only stereo.
Since 8.12.20 YT Videos only in 720p in an UHD TV (1 year old) This happens with all video with 60FPS. What the hell is google doing? Everything was fine and at the end of 2020 google want 720p max on an 4K UHD Android.TV? Hey google, do you want to sell more Chromecast sticks, or what is the reason?
Generally, if it works at the very moment, the YouTube App is quite OK to use. The UX of the YouTube app is a bit messy on my TV. The worst part is the un-stability: OFTEN (A FEW TIMES A DAY) I CAN SEARCH, BROWSE THE VIDEOS BUT WHEN IT COMES TO PLAYING THE SELECTED VIDEO (ALL OF THEM IF I CAN CONSIDER THAT) THEN IT JUST SAYS UNEXPECTED ERROR (IN MY LANGUAGE). The only way how to get out of this is the RESTART OF THE ENTIRE ANDROID (TV). The Force-Stop of just the YouTube App does not help!
Every time settings is selected app crashes.
I pay for YouTube Premium, but using this App I still get 1-2 Ads on every youtube video. The Web and Android (phone) YouTube Apps do not have this problem.
