Xfinity streaming not working

Xfinity streaming not working with my iPhone or ROKU.  I have updated, reset and powered off.  It has been down since yesterday morning.  I chatted with xfinity an hour and a half ago and they said this is a known issue and is being worked on.  They said it would be up for sure within the hour, but it’s still down.  What’s the issue and when will it be up?  Is there anything I can do in my end?
