Mircosoft Azure API $orderBy not giving the desired response

Question

I am trying to make the following API call and I expect ordering done based on createdDateTime, however this ordering is not done by Microsoft and I am still getting response in random order, any suggestions to make it work?

GET /v1.0/servicePrincipals/{0}/appRoleAssignedTo?$orderby=createdDateTime+asc
