Gateway and "View WiFi equipment" not visibile in the Wifi tab of the app, cannot adjust gateway settings

Basically the title.  Gateway is working fine but occasionally need to adjust settings.  The gateway does not show up in the Wifi tab of the app nor under "Xfinity devices".  I assume that has to happen in order to be able to select " View WiFi equipment", which I don't see anywhere.  Sure enough, using the web portal insists that I go back to using the app, so I am blocked right now.
