User Problem

If you're logged in with an account you never logged into at Trello, you'll see a screen with two buttons to create your account or not. You can't log in with a different account until you log out of your current email, having to access https://id.atlassian.com/login to log out.

Suggested Solutions

Add a button to switch accounts or log in with a different account.

Current Workarounds

Access https://id.atlassian.com/login and log out before accessing Trello.
