It seems like there are actually two entries on netflix for the incredibles 2
the incredibles 2
the incredibles 2 (spanish version)
Find the second one. It has options for both English and Spanish. But the LLN extension is not giving double subtitles, can you find out why?
You’re probably thinking “oh the spanish version probably just has Spanish so that is why”
But no, search the Incredibles 2 (spanish version) and you’ll see in the subtitles options that it has both English and Spanish
