I am using REST API to fetch all role assignments at subscription scope. I don't have the nextLink and still don't have full list of role assignments. I noticed this question has no replies either. So looking for any help with resolution on this. I used URL: https://management.azure.com/subscriptions/ID/providers/Microsoft.Authorization/roleAssignments. The missing ones were Owner role assigned to 2 users. Appreciate any help with this.
