Xfinity home app not connecting

I’ve had this service for the past four years, but in the last 6 months the home app has been trash. All it keeps saying is now connecting to your home/never connects. I can no longer arm/disarm from my phone…. ATP just disconnect the service 

I have also deleted and redownloaded the app and it still gives me the same message 

I can only view my camera from the regular Xfinity app but can’t disarm/arm or get any notifications when a door or window is open
