Hi @mjtilley76,
Welcome to the Roku Community!
In some cases, removing the affected channel and then re-installing it may help. To ensure the process is successful, make sure to restart your device before adding the channel back in. We would recommend doing this from the Settings menu by navigating to Settings > System > Power > System restart. (If you do not see a Power submenu, skip to the next step.)
For detailed instructions, refer to this Support link: How to resolve a channel playback issue
If you are still experiencing an issue and other channels are working correctly, and you only experience this issue on that channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it. You'll want to contact channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Please keep us posted on what you find out.
All the best,
Chel
