If you have access to multiple accounts, your user email must be the same across all sites so you can easily switch between locations.
For example, if you use @gmail.com at one site and @brandbot.com at another, you can’t switch between them in one account. You’ll need to log out and log back in with the other email.
To easily switch between the sites you have access to, click your initials in the top right > Select Account > select Location.
