Cant find games in my games and apps, pease help

I checked my order history and it's not on there, I only have one microsoft account. I dont remember if I bought the game or got it from xbox gold or the game pass.

That's very strange. It has been on a lot of sales in the past but even if you downloaded it with GwG, you would still have it as long as you still have Gold. And are you sure you're still on the same Region that you were on when you downloaded/played it
before? For instance, if you downloaded it from the EU Region back then and played it, but have since moved to America and are now on US Region, the game would not show up for you and it would not recognize that you 'own' it as they are different versions
in different regions.

Did you check if it's still in your order history? Also, are you sure you bought it with your account? if yes, I would contact support
support.xbox.com

If you did get it when it was on Game Pass, you would only be able to play it when it is in the catalog and you have a Game Pass subscription. Once a game has left the Game Pass catalog you have to purchase it so that you can continue to play it going
forward. I hope you are able to figure this out so that you can continue to play this title.

No I've always played from the US
