When I tried to log back into my existing Trello account, Atlassian presented an onboarding UI that created another, obsolete, new Trello account with the email address of my Atlassian account, which is not the same that I used for Trello.
Now I have to different Trello accounts, the one that I actually use, and the one that Atlassian created inadvertently. I have logged into both accounts, and I can switch between them. But how can I delete the unnecessary new Trello account?
