When I initially signed up, I added the main email address that I wanted to use. Then when I was setting up the account, it wouldn’t accept that email as the administrator. So I entered a temp address, thinking I could change it when I figured out how to use the preferred email. 

As it stands, I cannot change the administrator email address. And I can’t access the preferred email because it sends a verification code to the email I’m trying to access.

How do I change the administrator address?
