I've been running Plex on a new Roku 4 for a couple of weeks, with independent video and music servers. In the past three or four days, Plex has been very slow to switch between servers, has been slowing on boot, and has now taken to freezing altogether on boot, just showing the Plex logo. I just now did multiple restarts, power cycled the Roku, and finally had Plex come out of its coma after five minutes from boot to show me the music server.
Any ideas on this?
