@KrzysztofMoch @proohit This reverts the change in TheWidlarzGroup#4319, I don't think that change is correct. According to [docs](https://docs.thewidlarzgroup.com/react-native-video/component/props#selectedtexttrack) the default value for `selectedTextTrack.type` is "system" which means the video should respect user's preference in Settings > Accesibility > Subtitles & Captioning > Closed Captions + SDH. And this is exactly what happens by default without the changes in that PR. I think the author of that PR had this setting on, that's why it was showing the subtitles without setting something for `selectedTextTrack`, which IMO is the expected result. In order to explicitly turn off subtitles you have to set `selectedTextTrack={{ type: 'disabled' }}`. I tested it with this video and the settings option on and it works (disables the subtitles) -> https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8 Another reason why I think it should be reverted is because it also affects `selectedAudioTrack`. By default it should also have 'system' type according to [docs](https://docs.thewidlarzgroup.com/react-native-video/component/props#selectedaudiotrack), which means "Play the audio track that matches the system language. If none match, play the first track.", but the change in that PR turns the audio off by default unless you explicitly turn it on with `selectedAudioTrack={{ type: 'system' }}`. Fixes TheWidlarzGroup#4400
