After we performed the reset, you can connect the desired Google Ads account.
Please be aware that linking the wrong Google Ads account can happen when one of your Google accounts is still active in your browser.
To make sure you don't link the wrong account again, we suggest to log out of all Google related services (Google Ads, GoogleMail, YouTube, etc.) and clear your browser's cache, cookies, and history. Alternatively, you can also use the incognito mode in your browser. While using the incognito mode, you can log into Google Ads with your desired account and start the registration process.
