All streaming services ive come across are lazy af when it comes to subtitles. Non-english language in english movies not being subbed, literally no option for english subs that isnt hearing impaired subtitles eg. Wind blows quietly/door creaks silently etc.
its quite telling that sailing the seas offer better subtitle options than official services
