I can't get the script to work for https://disneyplus.disney.co.jp.
I changed the match string. I get an internet connection error message from Disney when I try to load the video with the script enabled.

Is there a known fix for Disney plus jp?

I didn't know there was a different version for Japan, but unfortunately according to this reddit post it's not possible to use this version with an international account so I can't figure out what the problem is. You can send me a private message if you want to help me fix it.
