I play this game with my cousin Microsoft Account ownership, logged in my PC MS Store.
I have another game (Forza Horizon) in own my Microsoft Account.
I can’t play Forza (ownership failed) if MS Store logged account is still my cousins’, I have to logout-login to my own account.
And I can’t play Flight Simulator 2020 too if MS Store logged account is still mine, I have to logout-login to my cousin account.
This method is quite troublesome.
Finally, I bought Flight Simulator 2020 with my own account so I don’t need switch account every time I want to play game.
The question is, Do I need remove installed Flight Simulator 2020 on PC first and then redownload/full reinstall again from MS Store now using my account?
Or after I switch MS Store to my own account, I can go straight fly with previous installation without crash/error risk (+ saving bandwidth and time) ?
