Gold Card Trying to redeem for Xbox live game pass

Yes the auto renewal is off already. I have the Game pass ultimate until May 25. I already bought a new 12 month xbox live gold card but when I try to redeem the code it says my 12 month
gold will be automatically convert to a 4 months xbox game pass ultimate which I don't want. I want the 12 month of xbox live without the game pass. Do I really have to wait until my xbox game pass expired before I can redeem a new xbox live gold (without
the game pass ultimate)?

Hi I just added $15 gift card to Xbox live and I’m trying to buy game pass but I entered the number on the gift card for game pass to redeem but it says it’s already redeemed

So my Xbox live gold card expired so I got a new one and redeemed it I go and try one of my games I know I need the live card for and it works for two days then it stops working so I guess my Xbox live gold card expired even tho I just got it I know this because all the games I need the card for don’t work a error thing pops up and says please sign in to account u redeemed or redeem Xbox live gold,xbox game pass. and then at the bottom it’s a button that says cancel and that’s it so am I going to get my money back for the card not working or can y’all fix this like what am I supposed to do I spent 25$ on this card and it don’t work

I had xbox gold does that automatically change to game pass core?

Yes, Gold became Core.

Any old Xbox Live Gold cards bought and redeemed now are also automatically converted to Core.

so from my understanding If I got purchased 3 years of xbox live gold,say even if I purchased these via 3rd party online seller which sells xbox gold cards and then redeemed these cards via my xbox one giving me years of gold then went and subbed to xbox
game pass ultimate for the 31 offer it'll give me 3 years of game pass ultimate subscribtion?.If I remove my card details afterwards I sub to game pass it wont lose the game pass after a month and go back down to regular xbox live gold membership for the rest
of the 3 years?..
