Hi, @DFarrOut
Welcome to the Roku Community.
We appreciate your efforts and time in the attempts to resolve the issue you've encountered with the CBS and CNN channels. We recommend reaching out to the channel provider's support directly and inquiring further about the issue since the issue has persisted despite the steps taken. Most channels on the Roku platform are managed by the channel providers themselves.
We hope for your understanding regarding this matter.
All the best,
Kash
