Xfinity app port forwarding STILL not working!

It's been well over a year and still the app will not connect under: Wifi/View WiFi equipment/Advanced settings/Port forwarding 

A unacceptable workaround was through the xfinity assistant but that method fails recently as you can't get to the network/port forwarding when typed in.  XFINITY if customers can't access their equipment in order to have devices function on our network...FIX IT!
