Hey Matthew,
Have you contacted the service provider to report the issue you're seeing with their channel, and request additional support?
We'd recommend trying the following process:
1. Remove the channel from the Roku device home screen by navigating to the channel tile, pressing the * key and choosing 'Remove channel'.
2. Go to Settings>System>System>System restart and restart your Roku player.
3. Once the device restarts, try adding the channel back once more from 'Streaming channels'.
If the issue persists from there, you'll want to follow up with the service provider to request they take a closer look at their channel, and provide further assistance to investigate the issue you're seeing.
Keep us posted if there are any other questions we can help with!
Thanks,
Tanner
