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.
Apparently it's due to the latest update to 9.4.0 build 4190. My TVs have been useless for almost two weeks. Youtube TV miraculously started working on my Ultra today out of the blue. I've tried everything. Still can't open 80% of my apps on my TCL tv though.
