Hi @DLB7.
A warm welcome here at the Roku Community!
Thanks for reaching out to us here regarding your playback issues with the Fubo app on your Roku streaming device. No worries; we're here to find you the best resolution for this.
We appreciate all of the troubleshooting steps that you've taken so far. It will be more effective for you to directly contact the channel provider itself, as it is the only channel that's having a buffering issue, as you've mentioned. It's best that you contact them through their FuboTV customer service page.
Let us know if there's anything else we can assist you with, and we'd be more than happy to do so.
All the best,
Carly
