I bought one-year menbership of ArcGIS for student use. But everytime when I login ArcGIS Pro, it displays that my ArcGIS online account is a public account, I feel very confused. I try to contact my administrator but the email was sent to my own email address, it seems that I am the administrator of my account. But I cannot assign a license to my own account. Could anyone help me solve this issue to use ArcGIS pro?
