Having difficulty with new user creation for one user:
New user was created from Admin - Users but no activation email was received by new user.
User record has application access granted for Jira and Confluence on their user record page and have correct groups assigned
Attempted to reset password but when user attempted they were told account has been deactivated in User admin this was not the case
De-activated and then activated user and when they then attempted to login they got the "Hang on, we need to verify a few things before you can log in." message with the comment "We'll e-mail you within a business day to help resolve issue"
New users have been set up and being able to access the application since this issue so seems to be user specific.
