SOLVED: Jellyfin -> Kodi sync woes

[jasep]

I've been a happy Jellyfin user for about a year until I had a crash. Here's my setup:

Jellyfin docker backend hosted on Synology NAS
Kodi frontend on Nvidia Shield (Android) using Jellyfin for Kodi plugin and Kodi Sync Queue plugin

Everything was working great until the external storage device that had my kodi info died. I thought that would be no problem I'd just reinstall Kodi with the jellyfin plugin and be good to go. But that hasn't been the case. After setting up my sources and installing the Jellyfin for Kodi plugin and letting everything scan, the watched status is not correct on Kodi with everything showing as unwatched. The watched status is correct on the web and the Jellyfin for android client, but for some reason it isn't correctly syncing down to the fresh Kodi install.

Can anyone help with suggestions? Everytime Kodi starts it displays "scanning for <media> using the <media> database python" message (sometimes TMDB sometimes TVDB sometimes both) and takes about a minute to get to 99% then stops, but the watched status is not correct. I'm not sure what I'm doing wrong. Also if I need to post a log, please let me know if it should be the Jellyfin or Kodi log (or both).

Kodi has a setting to scan the library on startup. This needs to be disabled. Jellyfin for Kodi kinda takes over the database and doesn't share well with anything else. When Kodi tries to handle metadata that Jellyfin is already handling it leads to some weird behavior. You'll probably also need to go into the jellyfin addon settings and do a repair library to do a fresh pull and update everything from the server.

Troublesome sync things like this are part of why JellyCon is generally easier for most people to use, at the cost of a bit of speed.

Thanks mcarlton00. I went and checked and scan library at startup wasn't enabled, but that led me to wonder why I was seeing it happen anyway. I realized I copied over an old advancedsettings.xml file into my profile directory which was really causing issues.

Everything is working now that I've cleaned all that up and did a library reset. Thank you for pointing me in the right direction
