Living and working in tech, I tend to keep up to date with stuff like this but honestly, I had no idea there was even a new UI being pushed for Plex, let alone the fact they've reversed it as per the link above! lol I've been a Plex user for eons, with lifetime Plex pass. For me, it's been one of the most robust and reliable things I've ever used. Literally the Plex Server app gets no attention bar the occasional update applied via the Shield Pro Plex app when prompted, and just sits there 24/7 dishing out content when needed. Even the Plex app on the Shield has been damn reliable for me and my family also. It's a part of daily life and has been for years. I am surprised to hear of so many people having issues with any of this. I'm sure there are valid reasons for all of it, or perhaps I've just lucky, but it's one of them things I don't even think about anymore. I turn the TV on, Plex TV is usually already open, I select what I want to watch and done.
