Ultimate And xbox live

If you subscribe to Game Pass Ultimate, your remaining Xbox Live converts into Game Pass Ultimate days. If the Game Pass Ultimate has run out you can either carry on with Game Pass Ultimate, or buy Xbox Live on its own. If you cancel Game Pass Ultimate
you lose any pre paid Xbox Live time.

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.

To contact them, please go to this site:

Yes, you can cancel Xbox Live Ultimate whenever and revert to only Xbox Live Gold.

So, when it says "Purchase of Xbox Game Pass Ultimate automatically upgrades your existing Xbox Live Gold or Xbox Game Pass membership(s) to Xbox Game Pass Ultimate at a conversion ratio each based on days remaining. Future
code redemptions are also subject to a conversion ratio. Conversion ratio subject to change. All conversions to Xbox Game Pass Ultimate are final: Once converted, you cannot re-convert your Xbox Game Pass Ultimate membership back to a previous membership.",
it means if you activate Xbox Live Gold subscription when your subscription of Ultimate is still active. ¿Am I right?

I think after activating ultimate, if you redeem a Xbox live Gold, it will extend your ultimate subscription.

Once you activated the Game Pass Ultimate your Xbox Live Gold was converted to Game Pass Ultimate time. If you cancelled Game Pass Ultimate, then you lose your Xbox Live Gold that was converted.

Xbox Live Gold is included in Xbox Gamepass Ultimate. You would only need to resubscribe for Xbox Live Gold if you were to downgrade from Gamepass Ultimate later.
