Plex Players

Server Version#: Version 1.41.8.9834
AppleTV Player Version#:8.45(9684)
Desktop Player Version#: web browser

I’m running the Plex server on the latest Debian system.

When I use it on Apple TV, Plex continuously has issues where Chinese subtitles
display as squares口口口, and when these squares appear, the playback speed becomes
very stuttered. When subtitles are turned off, there’s no stuttering issue.

When I use the Plex player on MacOS, there’s no such problem, whether subtitles are enabled or disabled.

I’ve tried downgrading the Plex server version which resolved the issue, because clearly this problem only appeared after the Plex server was upgraded to a certain version.

after upgrading to the latest version, the problem appeared again. I understand
this might be an issue with some connection between the Plex player on Apple TV
and the Plex server, but I don’t know how to solve it. Does anyone have any
clues?
