Jellyfin for Kodi not syncing from Kodi -> Jellyfin

[paradox115]

Describe the bug
Watch state is only synced from Jellyfin to Kodi. After watching an episode on Kodi, it gets marked as completed, but moments later will be overwritten by the state on Jellyfin and will be marked as unwatched.

To Reproduce

1. On Kodi, click to play an episode
   
2. Watch any amount of that episode
   
3. After playing the episode, wait a few seconds
   
4. On Kodi, see status of episode change from watched to unwatched
   
5. On Jellyfin, see that watch status is unchanged (still unwatched)
   
   

Expected behavior
After watching an episode in Kodi, watch status is synced from Kodi -> Jellyfin. Episode should be marked as watched in both Kodi and Jellyfin.

System:

• OS: Windows 10
  
• Jellyfin Version: 10.9.11
  
• Kodi Version: 21.1.0
  
• Addon Version: 1.0.5+py3
  
• Playback Mode: Add-On
  
  

Additional context
Aside from this add-on, I only have Arctic Horizon 2 as my skin for Kodi.
I am also using mpv as an external player.

Can you share the server side logs? And are you using other methods for tracking watch status? NFOs? Trakt?

[paradox115]

The codeblock above are logs from Jellyfin; here are some more with Debug enabled: https://hastebin.com/share/egaqififof.css.

I am not using anything else for tracking. As far as I know, the Jellyfin for Kodi add-on is supposed to handle all the syncing.
