Anything newer then 3.6 is hardcoded to use the google DNS - so circumvents services like Unotelly - so it will pick you up as a south african and you wont be able ti use Netflix
Had the same issue with my Chromecast as it is hardcoded to use the Google DNS. You just need to block the DNS on your router and it will work with the latest version of Netflix app no problem.
