i've lost my xbox ultimate game pass

You would still have the 3 years but you wouldnt receive the ,3months

You are capped at 3 years anything added after that is erased so it is better ti wait till 3 months is up then add

If you were below 3 years left the new games pass code should have converted to games pass ultimate and added on to your exsisting subscription.

If you were maxef out at three years it wouldn't be able to add anymore on.

It states that once you converted to Game Pass Ultimate, that if you cancel any converted Xbox Live Gold will be lost. https://support.xbox.com/en-US/billing/xbox-subscriptions/xbox-game-pass-ultimate-faq

It sounds like you signed up for Game Pass Ultimate, if this is the case when you cancelled it you would have lost your Xbox Live Gold as well, since when you sign up to Game Pass Ultimate it combines any Xbox Live Gold and Xbox Game Pass into the one
subscription.

Hi,

Once you upgraded to Xbox game pass ultimate, your Xbox live gold will be carried over to Xbox game pass ultimate. For example, if you have Xbox live gold for a year and you upgraded it to Xbox game pass ultimate, your Xbox live gold and xbox game pass for
console and PC will also be good for 13 months (12 months Xbox live gold+1 month upgrade Xbox game pass Ultimate). If you cancelled the Xbox game pass ultimate, automatically your Xbox live will also be cancelled since it is already merged to the Ultimate.
You need to contact Xbox Support to reinstate your lost membership.
