Things like subtitles and even audio tracks has to be the laziest mistakes by these companies. How hard can it be to copy all subtitle files to all folder in the CDN? (I know, it's probably a bit more complicated than that, but it can't be much).
If an movie doesn't even have the original audio track, it'll just lead me to unsubscribe faster.
Subtitles have copyright. Therefore, subtitles need to be licensed. Licensing is a shitshow, ergo Netflix does not have a license for EN subtitles in Japan, and does not care enough about its experience to reproduce English subtitles.
