xfinity app

Desktop PC, windows 11, Firefox

I'm unable to download the xfinity app. The download link at https://www.xfinity.com/apps does nothing. 

The brain dead chatbot just opens that page, no matter what I type if it contains "xfinity app"

I need to do port forwarding and the default gateway ip address  just directs to a message: 

"Managing your home network settings is now easier than ever. To manage your gateway settings and other features, please download the Xfinity  app."
