Hi everyone!
Please kindly check the email address that is signed in to the Zoom scheduler extension in Chrome?

Please also be aware if there are other Zoom profiles that are logged in to your browser. This issue typically arises when there's another profile logged in to the web portal and it was not properly signed out. When a user clicks a meeting link, the system will recognize the profile that is logged in instead of the profile of the host.
