I really want to Join Gamepass Ultimate but I'm at 48 months

Look, I bought a 1 month gamepass ultimate but the time is up. The problem is I don't want the gamepass ultimate but instead I want 3 months live gold would it allow me to buy it or would it just extend the gamepass ultimate subscription by 3 months

it will convert gold to 4 months gamepass ultimate, if you want the gold for the full 12 months let the gamepass ultimate expire first.

Are there different versions of Ultimate Gamepass? There is only one right? It's not like there is Ultimate Gamepass and then Ultimate Gamepass PC right? Its $16 a month for the Ultimate I have and pay for but anyhow it doesn't want to register on my Xbox
Beta app. It will take me to the store to purchase it for $1 (discounted then $14.99 a month afterwards) but if I go to the Xbox app, it will let me remotely download Gamepass games to my xbox. I literally just got into the CPU scene so i'm trying to troubleshoot
this

My friend bought me a 12-month gold as a gift. And right now there is offer at the xbox store to join Ultimate for 1$ but it's only a month. If i use first the code for gold and then join Ultimate for 1$, do i get a 12-month Ultimate subscription? Sorry
for all these questions but i'm a little confused since it's my first time and want to join Ultimate.

So I just entered the code to reload my account with 12 months of Gold, but when I did it, It instead gave me 4 months of Game Pass Ultimate? Is there a way to revert this? Because I don't really want the game pass, I just want Gold for the next year..

Did you already have an active gamepass ultimate subscription when you redeemed the year of gold? If so then thats why it converted your 1 year of gold to 4 months of gamepass ultimate.
