I tried taking off the email that was a guest from the main Trello account because Trello, when I tried to update it to that email, said it couldn't change the email because it was already connected to an account.
I need to change the main accounts email to the one it kept saying already had an account, and it's not letting me do so, even though I deleted that one from the Trello it still says it has an active account and can't switch.
