In ArcGIS Online, the Bio field is an editable field in the user profile with Active Directory Federation Services (ADFS) set up. When ADFS is set up with no first and last names, which is still a valid setup, editing the Bio field returns the error, "First Name is Blank". The first and last names are not editable.
