Guys, found this on Navigraph Forum, remember this works on MSFS2020, I apologize that I know nothing with MSFS2024.

The same idea I tried to use but changed the folder type to:
Steam Version:
%appdata%\Microsoft Flight Simulator\Packages\inibuilds-aircraft-a350
Store Version:
%localappdata%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\inibuilds-aircraft-a350
DELETE ALL THE inibuilds-aircraft-a350 FOLDER and restart the MSFS20, try to re-login to navigraph on OIS and it will be connected (at least for me).
I am hoping you guys able to connect using the same method.
Cheers 😁
