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.
I have Roku on a TCL TV and I have the same situation as the 2 viewers noted. I uninstalled and reinstalled app to no avail. Library works on mobile. Contacting YouTube seems like spitting in the ocean but I suppose it must be done.
