Before installing the update on iOS 10 the app was working perfectly, all of a sudden it stop working. Follow these steps and it should work as usual: Connect to your camera Wifi, on your right corner you would see a "i" select that and then copy your IP address into your DNS address go back to the SamsungSmartCameraApp and it should work as usual.
