It would be very helpful if you put in the option in the plex server configuration page to disable transcoding so you can force everything to direct stream, especially when you only have a low powered NAS.
Especially at the moment with this year long bug where plex transcodes videos the end device can actually play.
If plex actually fixed this and added that option I’d pay the $150 for the life long plex pass, but not willing to pay money while there is major bugs not being fixed.
