Problems with my Microsoft Account Suddenly?

It suddenly started saying i should log into my Microsoft Account as there is problem.
I do log in ok and when I try to look at my games (I’ve only got MSFS) it says I haven’t got any games !
Any advice would be appreciated.
John.

If you bought this sim through MS Store, you may need to logout/login to XBox Live (which includes Windows Gaming Accounts). That’s usually a good first step.
