Yes most likely.
So I tried the latest nightly for LE, I can't replicate what I'm seeing in the logs.. It works correctly with 4.0.12l (or 4.0.12k which is still available via kodi.emby.media)
Okay...updated to 4.0.12k. Switched back to Add-On mode and reset libraries. Unfortunately the Emby server still reports playback as having finished shortly after it starts even though Kodi is still playing the video. Logs attached.
Edited to add: After switching back to Native playback mode, Emby reports playback properly.
