Xbox General Options > Data > Online Functionality greyed out, GUI buggy (1.30.12.0)

I have factory reset my Xbox X, and done a fresh install of MSFS 40th Anniversary Edition Premium Deluxe - including the optional 60 GB of “Offline World” files.

On the initial configuration screen, even if you choose to NOT stream data, it says it requires a constant internet connection for authentication. Is this why my General Options > Data > won’t allow toggling Online Functionality to “OFF”?
