I was able to get mine working by performing a factory reset. I tried everything else as well. Can't be a Google issue if factory reset fixes the issue. It even reinstalls the same version of YouTube that didn't previously work. Odd right?
I have manually checked updates on my Roku TV and the YouTube app, restored the default theme, reset my network connection (forcing a restart), and unplugged the power source from the tv for 5 minutes, removed and reinstalled the app. Nothing has worked and YouTube is still not loading. Just flashes and returns to the Home Screen.
Have you tried the factory reset yet? It's a slight inconvenience reenter your passwords and all but I was having the same issue and tried everything suggested and only a factory reset fixed it. I'm curious whether or not it works for other systems as well.
@alanfog YouTube TV is not currently available on any Roku device. It's not specific to your TV. For users that had the channel before the Google/Roku contract termination, they still have it on their Roku device(s). But if they remove it, it cannot be added back. You can access YTTV through the regular YouTube channel. The icon for YTTV is at the bottom left of the main screen. But the stand-alone channel will only return if Google and Roku come to an agreement.

I have an out of the box thought. I have seen others have and have experienced this issue myself. I too tried all of these given suggestions with no result. My final action was to perform a factory reset with positive results, as have others. My next question is that if nothing in the updates or programming was changed, is there any chance that atmospheric conditions or maybe even sunspots may have caused some issue somewhere and and the factory reset somehow clears the problem. I'm no genius and I'm not a technician, so please excuse me for asking.
