Thanks for the follow up.
If this issue is only happening with a specific channel, I'd recommend reaching out to the channel provider directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on this 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.
Please keep us posted what you find out.
