Android TV App is really bad
It stutters, won't play 1080p or 60fps, the interface is very slow and laggy. The app used to be very good, what happened. This web-interface-api-nonsense has to stop. It crashes or stops mid-stream, if the stream starts in the first place. On my PS5, at least the picture quality is good (1080 60p), but it is also unstable and stops streams that work on my phone. Make a native app again, like on my phone.
Yes, I have noticed that issue with Twitch app on my (TOSHIBA_50LF621U19), Toshiba 4k Smart TV- Amazon Fire TV. I hope they fixed that issue soon.
