My Existing People Profiles, Assigned Devices, and Schedules for People w/ Assigned Devices are no longer accessible in Xfinity App

First of all ... ARRRGGGGHHHH

I have several household people profiles in my Xfinity app, and over 60 devices assigned to those profiles (kids, etc), along w/ scheduled downtime settings that have been working for over 2 years.

Within the last week or two, the Xfinity app is no longer showing me that I have profiles from the "Wifi" management screen in-app.  And I am no longer able to assign new devices to existing profiles.  Nor can I make any changes to existing schedules for my kids.

However, my profiles and scheduled downtime is STILL BEING APPLIED IN THE BACKGROUND ... but now I have no control over those settings.  Which is incredibly annoying.  This is the main reason I use the Xfinity app ... managing people, devices, and schedules.  And I used to make adjustments to schedules daily ... now I can't.

I have done the following over the past 3 days:

1. Uninstalled and reinstalled the app numerous times (no resolution followed)
2. Turned off private relay mode in iCloud, a new feature for my Mac and Apple devices (no resolution followed)
3. Called support and after 2 hours on the phone I got nowhere and had to explain the issue at least 5 times and nobody seemed to understand!!! (they scheduled a technician to visit my home)
4. A technician came to my home today and said he has no knowledge of the app, and therefore cannot help me .. said I should visit an Xfinity store (so, issue still unresolved)
5. Even tried creating a new people profile, but I'm unable to re-create any profiles or assign devices to new ones

I spend $330 each month for multiple services with Xfinity.  I am supposedly "Platinum" ... and the people, device, and scheduled downtime / uptime settings are the most important features to my family.  This issue has cost me over 3 hours of my time so far ... which is absolutely ridiculous.  I'm certain this is a known issue .. but nobody at Xfinity seems to have knowledge, or answers.

XFINITY APP TEAM ... I've seen multiple reports of this on Reddit, here, and via Google search.  You MUST address this or you will start to lose your best and most connected customers.  I am one of the customers you will lose if you don't fix this / apply yourself to these issues asap.
