Thanks for letting us know about this experience, Topa
Kindly try to perform the correct sequence to reboot this channel by removing the channel, restarting the device, and adding the channel. You can also try to check for the channel's update by clicking the star button on your remote.
If the issue remains unresolved, we recommend contacting Fox Sports 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 assist best.
If other channels are working correctly and you only experience this issue on the Fox Sports channel, that likely indicates the issue lies within that particular channel. In these cases, the channel provider must investigate the issue to help resolve it.
We hope this helps.
Regards,
Janadee
