The Wifi tab on the xfinity app is missing, I can’t access my router settings.

I can’t access my router settings on the xfinity app, the wifi tab is completely missing, the only tabs I have are the overview tab and the account tab. I have no way of adjusting my router setting now that you can’t simply adjust them on the computer anymore. I’ve been googling around for solutions to no avail. One of the only people I’ve seen online get this solved said to post on here and try get an upper level tech to look at my account. Any help appreciated thanks.
