ESPN Glitching. All other channels ok

Our ESPN and ESPN2 have been unwatchable for the last week. The 2 channels are pixelated and won’t play. We are using boxes on 3 TVs. All 3 TVs have the same issue. All other channels work and ESPN works on the Xfinity Stream App on the iPad.

I have done all the troubleshooting steps and reset our boxes multiple times

What can I do to fix this? I have only been able to reach a real person on customer service once and they said it would be a $90 service fee to come out.This seems to be an issue mentioned many times on these forums and is clearly Xfinity’s problem. Please help!
