I'm attempting to add an admin profile using the Create As Admin option on a constituent profile. However, there is no field to add the username on the Set Admin Username page. Why can't I add the username?
The inability to set an admin username will occur if the constituent record in question does not have an email address associated with it. To resolve edit the constituent record and provide a valid email address in the email address field. Alternatively, you can create a new administrator from scratch instead of using the create as admin option.
