Still needed with FW version 3.2.12?

[Richardrsb]

[Edit: just learned there is a newer version here: https://github.com/fabianishere/udm-iptv ]
Is this patch still necessary with FW 3.2.12? I have a UDM SE but i can't figure out how to get KPN IPTV to work. I could not find any configuration guide, and i am reluctant to test Fabians "patch" because it only supports FW versions upto 1.12.33. Also in newer Unifi network versions there is a setting: "Allow Internet Access" suggesting internet access is added to the isolated VLAN4, and thus enables playback, Netflix, and TV-guide... Any insights?
