Xfinitywifi and XFINITY (Xfinity WiFi Home Hotspots) SSIDs not being broadcast/can not connect

For over a year I have had many guests and family use the 'Xfinitywifi' and 'XFINITY' Xfinity WiFi Home Hotspot Guest connections with their own Xfinity login credentials in lieu of them connecting to my personal home xfinity wifi private network. Beginning mid July both of those SSID's stopped broadcasting from my XB6 Gateway. I ensured the feature was enabled (see screenshot), and even disabled and reenabled multiple times over the next few days to ensure it was flagged as 'enabled' correctly. After numerous Gateway resets and tier 1 support attempts at various workarounds 'Xfinitywifi' and 'XFINITY' SSID's just never came back. Finally, support suggested to send me the new XB7 gateway which I have now received and activated, sadly there is still Guest Wifi Network SSID's to connect to. Support says this scenario doesn't generate a ticket in their system after hours on the phone with them so they can not pass this issue on to Advanced Repair.

Can anyone here assist me with this? Now that I have family (and 2 friends) quarantining with my immediate family and I am working from home, its even more important that I let them use the isolated network with their own XFinity credentials.

Thanks in advance!
