There should be an option to change the mac address. There are iptv service providers that allow multiple device on the same account. Right now of the 6 licenses that I have I can only use one since I can't edit the MAC address. My provider allows 5 devices on the same account. So I have to use android boxes where I can edit the MAC address. Security as they said, should be left to the user for as long as they know that their service provider will blocked their devices if it is connected to multiple devices. Also for Samsung TV smart STb is very slow.
This is 2020, nobody should be using apps included in their tv....
