Xbox Ultimate Promotion issue

Hi so I just updated my xbox one with the new update and when I signed in, I saw a promotion on my dashboard for 3 months of ultimate for $1 with spotify and discord nitro included. I pressed to buy, but it took me to the main xbox ultimate page where the
price was still $15 a month. I restarted my xbox and now it's gone, but I went into the deals with gold section and and pressed on the button that says Xbox Live Gold and all these offers came up for ultimate for a dollar. Each one has the same result as the
promotion. Takes me to the xbox ultimate page where it says $15 a month. What's going on?

Any help would be appreciated cuz I was hoping to get a least a month of ultimate for a dollar but this kinda feels like a bait and switch. Could be a glitch.
