Played status when using an external player

[signde 26]

I'm using the latest "Emby for Android" app available in the Play Store on a Dune HD Pro 8K Plus device. The Dune HD device runs AOSP 11.

I have the Emby app configured to use an external player for playback which is the Dune HD player. I do this because Dune's player has deeper integration with the device allowing for use of the VS10 engine among other reasons. This works well for playback, I've encountered no issues and everything plays as expected.

What I have observed however is when using this external player, the played status of the videos never gets updated. I've noticed this with every video I've played going back a few months when I started using Emby on this device. I can watch a video until the credits roll and yet the status of the video is never updated to played.

Is this expected with external players on Android devices?
