Manage logs into wrong Google account when I have two Chrome windows for 2 accounts open

Click manage and then enter the login sequence and even if I log in to the Google account which I am logged into Cursor IDE and for which I bought Pro, it will log in in the browser tab under my other Gmail account and show me stats for that (how many fast requests I’ve used this month, etc).

Not sure if I understand you correctly. Do you have two Chrome windows open, each logged in with a different account? The latest login should override the logged-in account on all windows if it’s the same Chrome profile.
