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.
I did a search for the channel Zwift in the Roku Channel Store online and was unable to find a channel. We would recommend reaching out to Zwift to see if they have a channel available on the Roku device. Many channels on Roku are developed and maintained by the channel provider themselves.
Just searched Roku and found Zwift Challenge Cycling. It's described as "Action from the online training program that enables users to interact in a virtual world". Also says " * Not on Roku yet". Is this something new?
Hopefully Roku will soon have the Zwift app. Searched Roku for more info but found nothing.
For more information about that channel's availability, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
