Google pulls this same bs with consoles as well, both PS4 and Xbox One (S/X) have a shitty HTML5 app that just doesn't fit well with rest of the system.
Really? I've used the ps4 YouTube app a bunch to watch videos, and movies purchased from the play store. My phone can cast to it as well. Seems to work as well as the Netflix app. I've had more issues with the ps4 store app honestly.
