Hi, I’m European Spanish, and I can’t see any content with Castilian Spanish subtitles, because all the subtitles that exist in opensubtitles are from Latin America, and I can’t see anything with my language. European Spanish is very different from American Spanish. Please fix this problem.
When you go to their website the search box gives you the option for either EU or LA Spanish. Have you checked there to see if the video you’re looking for has a EU version available?
Only latinoamerican spanish
You can add requests if you want to get it added to opensubtitles. I don’t have much experience with them but it may be worth a try.
