Same issue here…
I just got my Shield TV yesterday and noticed that the Plex app is entirely different from the Plex app on my LG smart TV. Somehow I was expecting to find the same looking app…
I understand it’s not very supportive to complain too much, but I really have to add my own 2c.
Earlier I had problems with Plex not playing subtitles correctly (see this discussion and alternatively this topic where someone else seems to be fed up).
Also, playing from my NAS doesn’t work all too well with subtitles turned ON: the server isn’t powerful enough to transcode. Ok, a NAS isn’t suitable as media server, but I don’t understand why subtitles aren’t overlayed just like the menu or volume control is…
Now I have the Shield TV, which at least fixes playing UHD movies with subtitles, but now music doesn’t play!
I keep hopping from one problem to the next. There’s always something with Plex that doesn’t work right. Every update seems to change the UI, but bugs are unresolved for months on end (sometimes years).
To make matters worse: there’s absolutely no feedback from the Plex guys in these forums. We cannot file bugs in a bugtracker, we don’t know the state of reported issues. We don’t even know if people are actually working on any of these things. All we do know is that the UI keeps changing…
It’s sad, because I really like Plex and besides these types of pesky little bugs it works quite well. I even keep recommending it to people. But please - pretty please with sugar on top - fix those bugs and leave the damn UI alone!
