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.
Have you tried restarting your Roku device after removing the channel and before adding the channel? If yes, this is a good indication that there likely an issue within that specific channel that will need to be addressed with an update from the channel publisher. Channels on Roku are created and maintained by each channel publisher. In this case, you'll want to reach out to that channel publisher directly to share your feedback.
