This example is still relatively simple, but it should give you an idea: https://streamable.com/nj8fey
Good fansubs can sometimes do really crazy things, including replacing entire moving backgrounds.

Haha I'm to late :( Not available anymore. You sure it isn't about the external player used by jellyfin on mobile?

Cauz' I remember I had issues with .ASS subtitles only on mobile when VLC was used as external player.

Damn, I didn't know streamable is so crappy now...

Anyway, I've tried a lot of different players and they all struggle.
On the phone it's almost fine, but any Android TV Box just gets killed with a sufficiently complex scene.

I have no idea what streamlabs or Android TV boxes uses as backend player, but after a lot of debugging MPV solved all my subtitles issues on mobile (android) and desktop (Linux).

It made me kinda sad because VLC was the defacto application I installed on Windows for years !! But since I'm on Linux, MPV is the new standard in my default applications.

Maybe have a look if you can change the default player?

I tried a few players and they all have issues. :(
