DIRECTV for Business iOS App not loading anything at all.

After loading/logging in to the app, it sits at the "Retrieving Account Details" screen with spinning wheel for about 3-4 minutes, after which it moves to the Receivers page, but absolutely nothing loads.

I'm not talking about "Receiver Not Found" on my boxes (of which I have 40). Nothing loads at all.

On the settings, no receivers show in my Receiver Control, whether active or not. No Devices, no device IDs, nothing.

I have been using iPads and DIRECTV For Business Remote App for years in my sports bar. Sure, hiccups along the way, but I have never seen what's happening currently.

I have tried Logging out and back in.

I have tried deleting and reinstalling the app.

I have used 3 different iPads of all different generations from current iPad Pro to much older, running on separate versions of iOS.

My internet connection is solid and usable in every other way.

My DIRECTV Boxes all work and are providing content.

My DIRECTV account is in good standing.

My iPads all worked yesterday just fine displaying and accessing all of my boxes.

Help?
