Thank you for the info…
Yes I purchased and downloaded msfs from the Microsoft website and when I re-installed the other day I did it by logging into MS store and dnlded from there.
I’ve only used the same MS store account since making the purchase.
This is from my receipt.
The gamertag I had before the re-install is not the same after the re-install I was given something else and with that change I lost all my settings, purchase planes, etc.
