Issue with changed subtitles

[rs232]

I watched something today and realised the subs were offsync. So I logged onto my NAS where I have a subsync script based on alass that has been serving me for many years.

Logged in, synced, removed the old subs and went back to the amazon firestick player.

No matter what I do (rescan library, refresh metadata on that movie only, restart Jellyfin LXC, restart client) it still uses the old subs... like if they were cached.

Is there anything I can do to force my Jellyfin clients to fetch the new subs?

Thanks

P.S. If I force transcoding, only then it works but it seems like a waste of resources if that's not needed.

"refresh metadata" means you selected "replace all metadata" for the show/episode?

You can also try running the clean up cache scheduled tasks.
