R6 siege tracker automatically linked my old Xbox account and I can’t find a way to change it to my current Xbox account

So I just got the app for r6 tracker and when I tapped on “link account” it automatically linked my old Xbox account and I can’t seem to find a way to change it to my current xbox account. The only prompts I get are to delete or sign out of my tracker account. I just want to sign out and change my xbox account.
Any help on this problem would be greatly appreciated!

Did u try going to ubisoft sign in and doing the link or unlink option?

Hi, please try linking the new account through an incognito window, or sign out of xbox.com
