Doesn't work at all and the developer's website doesn't exist

Cannot open settings in Prime video's so I can't change subs as described.

best aplication for prime

prime pokazuje oryginalne napisy

unfortunately it is not working with prime and subtitles are not loading.

After trying several extensions, I finally found this one. Other extensions either don't work or only have Spanish/German. Only this one has Chinese as well as many other lesser-known language options(Chinese at the bottom, when I didn't find it in alphabetical sorting, I thought no, and then I found Chinese, so happy. It even lists all the script lines on the right and highlights the current sentence. Very much used. I really need it right now.

several countries use domain "primevideo.com", but the extension cannot parse the domain

it doesnt work with amazon prime :)

don't work with amazon !

Why in UK amazon prime, the subtitle shows in the center of the video and in very small size?

Simple but works well!
