Okay, so this entire season, each episode has two SRT files and one ass file, but once the video starts playing in the Plex iOS app, it acts as if there are no subtitles. And then, if you use the search feature to find something on open subtitles, it will act as if it’s letting you do it, but the subtitles still don’t show up.
If I open Safari on the same device and watch using the web app, the subtitles work just fine, the subtitles also work just fine on android, chromecast, and fire stick.
