Greasy Fork is available in English.
Allows you to download subtitles from Netflix
< Valutazione su Netflix - subtitle downloader
You should ask on the forum, in the Development subforum, not here. But if you want the answer specifically from me - no, I won't make a script for Disney+. I don't have an account there, I won't have an account and I don't want to rely on other people to give me an account when the script breaks.
Could there be a sub downloader for Disney+ ???
