Hi dev, i don't understand how "automatic" works. i'm working on a mobile app that uses AVPlayer that load an m3u8. in the subtitle settings i can chose for "no", "automatic", "italian"... if my device uses italian language i expect that if i choose automatics, the italian subtitle appear on the video but this is not working. There is any error in the m3u8? i'm missing some steps? i noticed that the automatics button doesn't work in this apple hls example too.. - https://developer.apple.com/streaming/examples/advanced-stream-hevc.html
