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.
We have several Roku Expresses in our home. We use YouTube TV as our TV provider. On one of our Roku's, YouTube TV suddenly won't launch. When we click on the icon, the entire Roku locks up and it has to be rebooted in order to move amongst the other apps. I've tried to uninstall and reinstal YouTube TV, but it is still misbehaving.
Have you tried restarting the Roku device after removing the channel and before adding the channel back? If you are still unable to resolve the issue, you'll want to contact Youtube support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
