Same problem here with all Android devices.
Unable to play movies with .ass subtitles. I have to force burning subs to be able to play those videos.
Play smoothly :
Xbox series X
Windows Plex client
MacBook pro
iPhone 12
Doesn’t play at all :
Galaxy Tab S7
Galaxy S21 Ultra
Nvidia Shield
Plex server hosted on Synology DS918+, and errors since last update.
Edit : everything went fine since I rolled back to previous android version of APK.
