Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
This just happened to me, too. I have a TCL Roku TV and have had it for the past 3 months with no issues. I have used YouTube TV without issues for 3 weeks and today, suddenly, I can't watch live TV nor on demand. The YouTube TV app works on my Roku Express in the living room, but not on my TCL Roku TV in my bedroom. I tried uninstalling and reinstalling the app. No change. WTH?
