Wrong Xbox account connected

I have 2 accounts and I connected the wrong one and now I can’t connect the correct one

Unlink the account don’t want here: Tracker Network - Manage Linked Accounts (thetrackernetwork.com)

You can also re-link the correct account on the same page however I strongly suggest re-linking on an incognito internet session OR fully logging out of your Microsoft/Xbox account before starting the linking process.

Microsoft has quite a strong auto-fill/auto-sign in feature that is likely pulling your old info in.
