You can download the official Plex app from the LG Store. Try to search it. It doesn't appear in the main page but if you write "plex" in the search bar, the two apps will appear (this offcial one and the PlayZ).

There's an official Plex app in the LG Store. I have just installed it and it's working fine. It's a great app:
