Cannot access my own game library

The console is set as My Home Xbox but it still will not let me access my own game library when not connected to the internet.

Do you have the console set as your Home console?

It actually works the same way the 360 did. You need a console license on the console to be able to play the games offline. The Home setting is what tells the console you have that license. Without the Home setting, your account has to be signed in so the system can check the servers to make sure you have a license to play the games.

Do yo own COD? None of the COD games are a part of the Game Pass Core library. You would need to own it to play it with Core or upgrade to Ultimate if yo wish to access it without purchasing the game.

I know whats happened and it stupid. All old gen games from 360 and Original Xbox dont show anymore, and can only be found in store. And any games that you do own, if they are in Games Pass, games with Gold or EA access they dont show in your library only
the library applicable to them. I had over 100 games in my library before a load of them being 360 titles. But no theyre gone, and some Xbox one games that i own dont show because theyre on the games pass. It waiting for xbox to fix the issue.

Sorry to hear it. Once a code is redeemed it cannot be used again and the item is tied to that account. To redownload the game go to My Games & Apps>Full Library>All Owned Games to see any game that you've purchased on your account
