There's a new Plex UI that they pushed to Android a few months ago that breaks everything, removes options and customizability, requires extra unintuitive actions to get to any self-hosted libraries, and pushes Plex's Live TV and other junk into prominent UI positions, as I assume the investors and MBAs demanded.
It was released and universally criticized. So Plex's team thought long and hard about that user feedback - ok, ok, sorry, I couldn't make it without laughing. They changed nothing and pushed forward and now it hit Roku, with no way to decline or roll back.
