Why doesn't Game Pass Ultimate work?

Hello, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

I’m sorry to hear you’re having some trouble when you try to use the game pass discount to purchase eligible games. Let’s try to sort this out.

However, before that, I would like to ask the following questions:

Did you purchase the subscription today, or when?
May I know if you tried to purchase the desired game, or games, using the Xbox.com website instead?
Is the subscription active on your account?
https://account.microsoft.com/services

The version for Ultimate is the same as regular Game Pass. Ultimate is just a way of bundling subscriptions. It doesn't effect how Game Pass/perks work.

Ik wil deelnemen aan de ultimate game pass maar het werkt niet

Translation: I want to participate in the ultimate game pass but it doesn't work.

Could you please explain what is the error you are getting when you try to subscribe to Game Pass Ultimate?

If you are using the same console and it is set as home for the account with Game Pass Ultimate you should be able to both have access to the games. If it doesn't work try having the account with the subscription logged in in the background and the other
account should be able to play the games.

If he claimed a gamed for gold game it's linked to his account and not yours and since he doesn't have a subscription anymore that may be why it doesn't work.

Hi there

Xbox games pass ultimate games to be connected to be online to be sure it's the correct licence, that is why it won't work in offline .
