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.
When problems are confined to a particular channel, such as Fox News, it may be that the channel app installation has gotten corrupted. A reinstall may fix the problem, so give it a try. Remove/reinstall procedure:
Highlight channel on home screen.
Press * key and choose Remove channel option.
IMPORTANT- DON'T SKIP: Restart the Roku to clear its memory via Settings > System > System restart. (On a Roku TV, this is Settings > System > Power > System restart.)
Reinstall the channel. Note it will be added to the END of the channel grid.
If channel requires a login, you may need to log in anew.
Beyond that, though, you need to understand that the channel owners create their own Roku channel apps, provide them to Roku, and maintain them. The only channels controlled by Roku are their own Roku Channel and Roku Media Player. For other channels, Roku just provides the platform on which they run. Problems in how a particular channel operates should be directed to that channel.
