Sorry that you are having a frustrating experience with Azure Files. I will pass on this feedback to the Azure files team. It sounds like you might not have the proper RBAC role assigned. Can you doublecheck that you have assigned the Storage File Data SMB Share Elevated Contributor role? For more information you can refer to this page.
Hope this helps. If this doesn't resolve your issue please let me know and we can work with you furhter on identifying the issue.
