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.
For more information about that channel's functionality, 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.
I use a streaming platform- tyson tv- and it just disappeared from one of my roku devices (but not the other on a different tv) and when i got to add the channel back i get "could not add 'tyson tv'. error"
i've restarted it several times, got all software updates and yet this problem continues-
