My older digital purchased games not showing up in my game library.

Hi, I'm Luis a Xbox user just like you. Thanks for reaching out us here.

Are you completely sure you are using the same account you bought those games with?

If you are let's first try deleting the account's cache

Have you tried clearing the MAC address?

Well, Battlefront 2 and Recore are showing up on my digital purchase history. Both in 2018. But they are not on my Xbox. Recore happens to be in my PC games library, because it is an Xbox exclusive and it goes to both systems. There is quite a vast majority of my digital games missing from the digital purchases link you posted. Not sure why.

Do the games not show up in the games library of the new console when the account that purchased them is signed in? These are all digitally purchased games and not disc based installs, correct?

Same here. Interestingly, In my orders it shows that I purchased the digital deluxe, but in the store and on my games library, it's changed to just the series x version.
