Game Pass Ultimate (Alpha Users who couldn't add codes)

If you're in preview alpha or alpha skip ahead, search for Xbox Game Pass Ultimate and you should be able to join.

If you had Xbox Game Pass Ultimate already active before you redeem that code, when you enter a code for Xbox Live Gold or Xbox Game Pass it will add as Game Pass Ultimate and not only Xbox Game Pass, is this your case?

I'm in preview Alpha and have subs to both Gold and Game pass. Where can I find the ultimate game pass?

If you add a prepaid Gold or Game Pass card while you have a Game Pass Ultimate subscription, the Gold/Game Pass is converted to Game Pass Ultimate at a conversion rate based on the price of the subscription, not the time 12 months of Gold is equal to
the price of 4 months of Game Pass Ultimate. In order to add a prepaid Gold (or Game Pass) and get the full time, you would need to either cancel your Ultimate subscription or wait for it to run out and then add the code after the Ultimate subscription has
ended.

You can add the Xbox Live Gold and Game Pass code then upgrade to Ultimate. The Ultimate will automatically be extended by the amount of months of the Xbox Live Gold plus the amount of months of the Game Pass code.
