Profiles for clients

Back in the Plex 3.5 client days there were profiles for the various devices. Now with the latest, do those files still exist somewhere?

Which profile would an iPhone 6 use from the server/Resources/Profiles? It appears to be the iOS.xml file, can you confirm that would be the one? Thanks

Any chance I can get help copying a profile to my DS918? I logged in via ssh but cannot seem to find the directory or u derstand how to get the profile from my Mac desktop to the ds.

Thanks

The location for custom profiles, which you must initially create yourself, on Synology, is: '/volume1/Plex/Library/Application Support/Plex Media Server/Profiles'

Once the directory exists, and a properly formatted XML profile has been copied in, with ownership changed to plex:plex, restarting PMS will activate the profile.
