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.
You are not providing enough information. What are the model numbers of your Roku devices, how many do you have, and exactly what do you mean by not showing up? Is the channel icon only appearing on some devices and not others? It's possible that the channel isn't supported on all devices. They don't provide that information on their info page, so that's just a possibility.
