It comes with my Hisense, but it’s just a **** app.
I used Plex a few years back when I had an XBox purely for the 4k, but the UI was just so kak I went back to emby which at the time had not been given the required access by MS to support 4k.
It was better to watch 1080p than deal with the garbage that is Plex.
As it comes with my TV I have it another bash a month or so ago and the setup was a pain, the UI is in no way remote friendly and my TV, which was the reason I went through all the effort was the only device that would not connect to the server.
That app is just a ****ing joke.
