Has anyone tried to use IOS 11 to read subtitles in films where there English subtitles? I have had really no luck getting this to work. I have tried this feature with YouTube vidios and on the PBS app. I have the rotor setting to speech on that media content thing that's new. I can however get VO to read the closed captioning for the deaf but not subtitles. Please post if you have had any better luck than I've had. Thanks very much.
