r/IQIYI

I just got IQIYI on my Roku tv , it seemed fine until I tried to watch Righting Wrongs but the subtitles wouldn’t work. I played the same movie on my phone and the subtitles worked just fine. The subtitles worked fine for every other movie on the app, but for some reason they don’t work on any movie from Hong Kong on my tv. How do I fix this issue ?
