If you've got it working then obviously it must be possible, but I'm a touch confused because the ErsatzTV documentation says "A Plex Pass is required for ErsatzTV to work with Plex." (https://ersatztv.org/docs/user-guide/configure-clients https://ersatztv.org/docs/user-guide/configure-clients) Is it possible that you had this working in the past but Plex has since removed the functionality from their free tier?
