A new setting introduced in Configuration/Roles and permissions - Prevents logged-in users from editing their own user profile form in AP. This setting will only be enforced when this setting is checked for a certain role and will not apply to the super admin, who can always view and edit all their properties. To enable these settings, go to Roles and Permissions, find the role for which you want to apply the settings for. Then check the setting Prevents logged-in users from editing their own user profile form in AP under Entity Actions/Persons.
