I have changed which email address was tied to my team account vs. my committing account. So after initially connecting team "sisproject" to "firstname.lastname@example.org" and having no email on my user (not email): "email@example.com" I went to my team profile and added firstname.lastname@example.org as a new email, confirmed it and then set it to primary and deleted the email@example.com from the team email.
After that I added firstname.lastname@example.org as contact email on my account email@example.com. Now I am unable to confirm it as it gives me: "We were unable to confirm the email address. The validation email may have expired." every time I try and resend a confirmation email.
