Just upgraded cold war from last gen to series x edition and can only reach this screen...

From what I can tell, to access the Series X version of the game, you need the Cross-Gen bundle...once you buy that, you should then be able to download and install the Series X version. Without the cross-gen bundle it will, presumably, just install the XB1 version

From the Store page:

"For digital owners of the Call of Duty®: Black Ops Cold War Standard Edition, this upgrade will unlock the Call of Duty®: Black Ops Cold War Cross-Gen Bundle, giving access to the Xbox Series X|S version of the game. After upgrade purchase, search in the Xbox store for the Call of Duty®: Black Ops Cold War - Cross-Gen Bundle to install the Xbox Series X|S version of the game."

Hi,

You have to pick up from the store the cross-gen edition and it will cost you the difference between the standard and the cross-gen version (around 10 bucks) :

This is the product that is the upgrade from Xbox one Cold War to series x version

Hi CarGuyB3N.

Cyberpunk 2077 will download the Series X updated version free via. Smart Delivery, but
note that COD: Cold War will not if you have the Standard Edition, but you will still be able to play it without the Series X upgrade. You either have to buy a digital upgrade or purchase the Cross-Gen or Ultimate edition of the disc release,
to be able to access the Series X upgrade download.

Hi!

Maybe you have the Xbox One version of COD Cold War and you see that message because the Xbox One version cannot be upgraded to Xbox Series X. You can find more informations about COD Cold War editions here:
