Xfinity App Does Not Show Gateway Device Despite Active Internet Connection

My internet connection is working fine.

However, when I log into the Xfinity App, I do not see my Gateway, nor any Devices. This is a huge issue since the Xfi website has been decommissioned, and even logging into my router's admin portal via 10.0.0.1 does not allow me to change any settings - all of this functionality has been moved to the Xfinity app - the same app that is not displaying my Gateway.

Again, my internet connection is fine, and have internet service. However, my Xfinity Gateway does not show up in my Xfinity App - in fact, there is not even a "devices section" in my Xfinity app. There is no way for me to change essential settings (such as ssid/password update, port forwarding, firewall, etc) because they have been stripped from every other place that they could be accessed, including when I directly sign into my router via 10.0.0.1.

See screenshot of Xfinity application below. There is no way for me to access my Gateway or change my Gateway settings - there is no "Devices" section despite my internet connection working fine. I am renting the official Xfinity Gateway.
