Xfinity App hangs at the WIFI module with a wall

update:

this was finally sent to a developer  department and is now fixed

my first thoughts on this must have been correct

Scenario
- I live in a one room studio apt, with one wire coming in to connect to for internet.

- I have Xfinity Internet only, no tv, etc..  I only use internet to stream shows/movies and podcasts, no gaming.

Initial Problems

1-Some of my devices were not getting connected or audio would go in and out,  or having problems staying connected.
2-Xfinity app showing that other devices are connected (not mine), some are 'hardwire' connected (wtf?)  Note: I have no hard connected devices, ever. 

    Then I renewed my contract, and was sent a white modem to replace the black one. 

      Same things happened.

Finally a tech guy comes out and takes a look at my wire coming from the box outside.  He puts it on a meter and shows me it has tons of holes in it.  Maybe because it's 35 years old?  

Wire is replaced, connection perfect, all my devices are working. 

But I still have a problem, Xfinity App says I am not connected if I try to view/edit Wifi or devices under Wifi.

And since I'm "not connected"  (but I am CONNECTED and everything is working great)   I can't get in to the wifi component that is listed at the bottom of the app screen, to view my wifi or view/edit my devices.
I cannot login on my laptop and get to this screen as it says to do so I must use the Xfinity app. What a loop.

No agents have a solution, 
and I have suggested that this Xfinity APP must have been overloaded by connections at some point and that has caused it to 'hang' and keep a constant 'your home internet is not connected'  wall in my app, and keeping from going any further to view wifi or view devices. 

What do you all think?
