UPDATE 2335Z:

///////////////////
We are aware of user reports of long initial loading times to get into Microsoft Flight Simulator 2024 among other issues.
With so many users initializing the sim concurrently, we have a large number of server requests. We are actively working to resolve the issues as soon as possible.
For support updates, please visit the MSFS Support Twitter page as well as our Known Issues Web page.
We appreciate your patience and understanding while our teams work to get everyone in the air.
Thanks,
MSFS Team
