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.
Many (most? all?) channels you subscribe to via Roku (as opposed to directly with the channel on its website) can only be viewed via The Roku Channel on a Roku device. Your subscription is with Roku, not the channel, so typically you can't view through the channel's own app or on non-Roku devices.
