Updated Jellyfin in Synology Docker, apparently wiped cache/config

[Efficient_Good_5784]

Could it be as easy as changing the /cache volume1/docker/Jellyfin/cache and /config to volume1/docker/Jellyfin/config ?

No because that's where your current config folder is located at.

For this problem, we can ignore cache as it's not that important to lose.
What is most likely the issue is the config folder.

I'll run some tests later when/if I have time, but my guess as of now is that config is the issue.
