Advertisements so, i can confirm (for me anyway) that it is the youtube app that has made the stream 4k basically unusable after tivo forced this latest trash update on all of us and then went radio silent. every time i reboot, i end up with the youtube app freezing the second you try to play anything and video in every other app (no joke, literally every other app does this) is so choppy that everything is unwatchable. the device is basically a brick at that point. here's what i've come up with so far to at least make the device usable (unfortunately though you have to do this on every reboot...or at least i have, i haven't found a way to make it stick over a reboot yet): go to android settings > apps > youtube > force stop, then uninstall updates go to google play store, click your profile icon at the top of the screen, and update the youtube app at this point, the youtube app should now work again and video in other apps will be smooth again. i have absolutely no idea why or how this is happening, but this has worked for me. i can't speak for it fixing the youtube tv issues, but if anyone is willing to test it out go right ahead. also, if anyone could figure out a way to make this stick across a reboot or figure out what the hell tivo did to bork this update so badly, that would be much appreciated...i tried just disabling the youtube app, that didn't work. even after reboot the problem persists until i re-enable and then do the uninstall updates / update dance with the youtube app.
