Plex doesn’t use profiles anymore if the app already exists for the host which can communicate the player’s capabilities.
The idea behind profiles was how to have a basic app. The profile then told PMS what the device can do .
Since those days, profiles aren’t needed.
The app communicates with PMS at the start of each playback.
In your logs you’ll find MDE: entries. This is the player telling PMS two things:
– 1. What its capabilities are
– 2. What it wants to play (including options)
This exchange does what profiles used to.
Bottom line, If you have an App now, you don’t need a profile.
