Remote players are ALWAYS transcoding to SD. It says fully accessible, I’ve doulbe checked the manual port forwarding is working. At my wits end here. It was working before and seems to have just stopped…
Just to double-check… the screenshot from your original post displays the connection as remote (not indirect).
Do you have any restrictions for remote connections on those clients (e.g. Plex remote video quality or some limitation on the mobile OS)?
