How does this work if my user is created by my application via Management API call in an Auth0 Database, and not via an IDP? I do not allow sign-up or associating of the account to any accounts generated by a third party identity provider. I cannot find options around Connection Sync. Yet, I still receive the “Your account is not allowed to update the following user attributes: family_name” error, and I do not want to do the metadata+rule workaround unless that is a last resort.
