Subtitles keep on disappearing.
I like watching with subtitles. But the computer and the iPhone are pretty sure I don't. I often have to repeatedly turn subtitles back on during each episode of a show, or multiple times in a movie. I just watched The Martian on my laptop, and had to toggle the subtitles off & on & off & on again (This is known as usually a way of getting subtitles to stay on) no less than three times during the movie, because they kept just disappearing. When I checked, they were turned off again, and I had to turn them on. This has happened all the time on my phone, and sometimes on the TV when I'm actually home watching things. I can look away when it was working, and when I look back seconds later, the next character isn't subtitled, and so I then check, and I have to turn subtitles back on again.
You can set the language to a set language, but there is no "subtitles always on" in settings that I can find. How can I permanently force subtitles to remain on under all circumstances please?
