Watched state issue - NFO files

[Lars Christian Gamborg]

So I am using a Jellyfin client (webOS). I also use TinyMM for organising my movies. I use NFO files and I disabled scrapping movies on my server (only reading from the NFO files).
I prefer to update my info about my movies using TMM, and also my Watched state. 

Somehow it seems like that Jellyfin server doesnt always pick up the Watched state from NFO files, and more than often it doesnt write the Watched state back to the NFO files, after I watched a movie. After watching a movie on the client side, it does display its been watched in the Library (just not tagged correctly in the NFO file). 
I tried to rescan my movies, optimizing Jellyfin, Clean Cache directory, Clean Old Sessions, delete the NFO file and write a new one, rebooting the server and rebooting the computer. Nothing seems to help. 

Is this normal behaviour - is Watched state stored somewhere else in Jellyfin? Is it not supposed to be stored in the NFO file?

As I said, I prefer to organise my movie info with TMM. Its just a lot quicker, so it would be nice to find a solution to this. Is there some setting in Jellyfin I forgot?

By default it is stored in the jellyfin database. You have to configure Jellyfin to write the watch status to NFOs.

Dashboard > Libraries > NFO settings

And you can only have one user write to NFOs for watch status.
