I am an Org & Site Admin trying to remove an Org & Site Admin who recently left our company. When I go to admin.atlassian.com, it takes me straight into my organization's settings that start with Users. There is no options for Administrators. The help tip for removing the user from the admin group gives the same instructions as you, so I don't know why I'm not seeing it. Did the interface change, or am I doing something wrong?
