Game pass ultimate not showing on my account

My girlfriend had recently got game pass ultimate and we said we would gameshare it. Her home xbox is my xbox and my accounts home xbox is on her console. The subscription is only showing up on her xbox and is not transferring to mine also how do i fix this?

Gamesharing through the "Home" feature does not share the Ultimate subscription. "Home" console lets you play any of her purchased and downloaded games even if they are from Game Pass. Your account will not show as having Ultimate, and your account will not be able to utilize Game Pass PC or cloud gaming. Those features are only for the account that actually purchased Game Pass Ultimate.

The solution is most likely just time. The system needs to update and reflect what the account actually shows. In the case of the Game Pass Ultimate conversion process, it will indeed show that your subscriptions to Gold and/or Game Pass will be canceled,
with the Game Pass Ultimate subscription replacing it.

Its the same Account on my XBox and on here. The Subscription doesnt show up there too. Does my Subscription stop when i purchase xbox game pass ultimate? Maybe thats why its gone cause my XBox game pass ultimate just expired

it shows No purchases made in the past 3 months but on my bank account it took my money for one mounth xbox ultimate game pass

Only the account that purchased Ultimate will show as owning Ultimate. Any other accounts using the Home console of that account will be able to play online and access any games that account downloads. They will not have access to Game Pass as Game Pass
does not share, but the games downloaded from it do.
