Strange location problem

Brand new customer here. My account seems to be in two different cities--It's as if there are two variables in the system, one for which channel guide I see, and one for whether I'm allowed to watch local content.

Here's the background... My building's HOA in Florida is providing DirecTV service under an MDU "bulk" agreement (which I helped them set up; we went live two days ago). Most of the building residents are snowbirds, like me. Denver is my home most of the time. I set up my account a couple days ago, from Denver. 

What's happening is that I see the Denver local stations (ABC/etc.) in the channel guide, but I am unable to watch or record any "truly local" Denver content, like the local news broadcast, the local sports teams (e.g. Colorado Rockies MLB), or anything at all on channel 20 (KTVD, which is a local Denver "independent" station). It says "Looks like you're travelling" (nope), or the content isn't available except for local residents (which I am). This is true on almost any device. It's the behavior on my brand new Gemini box, both our iphones, both our ipads, two Rokus, an Apple TV box, a Firestick, etc. etc.

What's weirdly different is on a PC in any browser (Chrome/Edge/FIrefox) I get the Florida channel guide, and I am able to watch local Florida content, like Marlins MLB games (both live or recorded). Strangely, if I record, say, a Marlins game, I can see it in the library of recorded shows in a PC browser, but I can't even see the existence of the recording on any device that shows me the Denver channel guide. If I try to record Rockies games from a "Denver channel guide" device, or Denver news, it says sure, it will record them -- but just doesn't. When I set up the account, it suggested the Rockies as my local team, so it knew I was in Denver.

My credit card billing zip code is in Denver. My ip# as shown in the location settings on e.g. the Gemini shows my correct Denver comcast/xfinity internet ip#. If I tell the Gemini to set my home to my current location, it says I'm already in my home location. My credit card billing address was initially for a PObox mailing address here in Denver, so in case being a PObox was the issue I changed the credit card to one where the billing address is my residence zip code (also in Denver, just one digit different in the zip code) -- nope. No change.

I tried connecting via a Denver area cell phone ip# (i.e. turned off wifi on my phone), no difference. I've tried a few other off the wall things too, no luck.

I've tried all the usual things like rebooting/resetting things (but, really, they're all brand new installs, so this was just to dot the i's and cross the t's). I'm pretty tech savvy (like, a Ph.D. in CS and done networking and writing OS's for a living), so I feel like there are a couple conflicting settings in the system, but as a customer I can't see or change them. If I could just see their database or the source code for the system! 😊

I called tech support, we did a video chat where she could see what was on my screen, etc. She had no idea what the problem was. I'm not sure she knew what a bulk agreement was, though, so this seemed above her level of expertise. (Reboot things, etc.)

So, I'm in a weird half & half state. From the level of comments here in the forums I get the sense there's a lot more expertise, so I thought I'd post.

Any ideas???  Thx.
