Hi @MarylandMom,
Greetings from the Roku Community!
We're sorry to hear about the playback issue with the channel.
In some cases, removing the affected channel and reinstalling it may help. To ensure the process is successful, make sure to restart your device before adding the channel again. We recommend doing this from the Settings menu by navigating to Settings > System > System Restart > Restart.
For detailed instructions, refer to this Support link: How to resolve a channel playback issue.
Please let us know how it goes!
All the best,
