This just started happening yesterday (11/18/2021). The YouTube TV app on both my Roku players keeps freezing after a few minutes.
At first, I thought it was an issue with the player, so I reset it. Still kept on doing it. It was just fine the day before. I was going to remove and reinstall the app but I'm glad I checked. The app is no longer available even though all news articles say that it won't be removed until December 2021.
Is anyone else experiencing this? And if so, do you have a fix? If not, what's up Roku? This isn't an app issue since I can watch it on my computer/phone just fine.
