xfinity app errors in advanced wifi settings

I am trying to set up port forwarding.  However, when I go to the port forwarding page in the xfinity app in "Advanced Settings", it just says

Something unexpected happenedWe can't display your details right now. Please try again or come back later.Try again

This has been happening for 2 weeks.  Also when I go to the "LAN & WAN" page to find out my IP address, it just says 

We encountered an Issue.If the problem persists, check back later.Try again

again, happening for 2 weeks.  "Support" is no help, the AI chat doesn't understand any questions about this and refuses to connect me to a live person.
