I regret exchanging points for an xbox live gold subscription. Is there a time limit on the...

Hi, in my experience, there is no time limit/expiration on codes for Xbox Live Gold and/or Game Pass from the Microsoft Rewards program. I last redeemed such a code over a year ago and as such, I would probably double-check the text in the email that contained
the code just in case there's any newer language in there that would say anything regarding expiration, but unless otherwise indicated there, it should be perfectly fine to save the code and redeem it at a later time. Hope this helps!

I think this opportunity is temporary. Microsoft can and probably will stop the possibility of exchanging game pass and live gold subscriptions for game pass ultimate, since the price and subscriptions are not the same. Few xbox users will buy a game pass ultimate subscription with the possibility of free exchange for example: live gold on ultimate!

Hello,

I am sorry Xbox Live Gold is Required for All Multiplayer Games on the platform.

You can earn Point from Microsoft Rewards and exchange them for Xbox Live Gold
