When setting DNS in the app using the saveToPreferencesWithCompletionHandler method of NEDNSSettingsManager
(1) After setting in the app, the user needs to manually select the set DNS in Settings App -> General -> VPN & Network -> DNS. Is there a way to do this automatically in the app?
(2) Besides the above, is there any other way to automatically configure system-wide DNS from the app?
