Completely agree. I have the premium deluxe edition which cost over £100 so it’s unacceptable that as soon as the server fails I can’t use MSFS.
I accept that it’s not the flight sim teams fault but something needs to be implemented to allow users to continue using a game that they paid for.
Perhaps something such as the sim allows the user to use the software for 24 hours before trying to recheck the licence would do the trick.
