Can I play both the xbox one and the Series X/S at the same time?

Both games use smart delivery, so can only download the Xbox Series X|S version of the game on the Xbox Series X|S. If you want to play the Xbox One versions, then playing on the Xbox One is your only option.

Ok, then can I have both versions installed and still play them separately on the Xbox series x

Hi SteveVincent1, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regards to your concern.

That's not possible, you can only play one game version at at time.

All Xbox One games are compatible with the Series S/X. You can't sign in and play them at the same time on both consoles if that's what you mean though, but you can switch back and forth between the two consoles.

The digital version Flight Simulator 2020 is an Xbox Play Anywhere title, this means that if you purchase it on the Microsoft Store or Windows Store it can be installed on both systems.

I'm afraid if your Laptop does not meet the minimum spec it won't work on your device. If you buy an Xbox Series X or Series S and use the same account you can install and play it on there.

Note: The console must be a Series X or S. MSFS2020 is not compatible with the older Xbox One, Xbox One S, or Xbox One X
