We see LOTS of complaints here about the the app Xfinity supplied for Roku.
When problems are confined to one channel app, there is a chance the channel installation has been corrupted and it needs to be replaced with a fresh install.
- Highlight channel on home screen.
- Press * key and choose Remove channel option.
- IMPORTANT- DON'T SKIP:
From home screen, Settings > System > System restart. This assures no remnant of the old installation remains in the Roku's memory so you get a complete reinstall. It may or may not make a difference, depending on what's causing your problem, but it's worth doing.
- 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.
