Insufficient privileges to complete the operation while update via azure graph api

Question

I'm trying to update users profiles in azure via graph api. When it comes to "mobile" attribute I receive the exception: "Insufficient privileges to complete the operation". Many attributes like city, streetAddress or telephoneNumber are updated successfully with the same portion of PHP code. Is this a configuration/schema problem?

Answer 1

In my test, I promoted the permissions of the app accessing to WAAD, as the figures show:

and

And I sign on the application with an account as an administrator of organization,shown in the USERS=>{user_name}=>PROFILE=>ROLE section.

Then I can update user profile with mobile phone with any format. If the mobile phone number should be with country code, the number format should better be like [phone].

BTW, in my test, after configuring the permission of application, I waited for almost an hour since Azure AD seemed to cache the old permission.
