How to remove my old GT from xbox games?

It is Apex legends, thank you.

i know some old games like 360 games the new tag system is not fully compatable, if its on new games i would contact support. (if you can)

can take upto 72 hours to fully propogate across all services.

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

The game will only be removed from the store. Probably to prevent people from buying the old version by mistake.

Clean your console's MAC, look for the game in the store or your library and try installing the game again.

Network Settings> Advanced Settings> MAC Address and Clear.

Every item downloaded to your console has two DRM content licenses attached to them. One for your account, and one for the console. All of the content licenses for the games you have downloaded are still attached to your old
Xbox (even when your account is removed from it). You will need to transfer that license to your new console.

Here's how. Sign into your Xbox One console > Go to the "Settings" page > Select the "My Xbox" > Select "My Home Xbox" > Select "This is My Home Xbox".
