Hi @mna,
Thanks for getting in contact.
Sorry to hear about your experience. If you are still unable to play videos from one channel after attempting the suggestions above, videos from other channels play fine, contact the channel provider's customer support team to report the issue and get help. Channels on Roku are maintained by the channel developer themselves.
In this case, there's likely an issue within that specific channel that needs to be addressed with an update from the channel developer.
Regards,
Nimfa
It is my sincere recommendation that you REMOVE CBS app from your offerings. YOUR customers are frustrated with the issue and with YOUR inability to fix it. Removing the app will save us all a lot of trouble.
