I don’t know if it can be called a bug, but it’s annoying, as it’s impossible to know which is the real good answer. Let me explain!
In German, “sie sind” and “Sie sind” are pronounced the same, but the meaning is different. There’s an activity where you can hear the words and you must choose which is the correct answer… (the words in German, or the translation into Spanish). When you hear [sie sind], and among the answers are “sie sind” and “Sie sind”, it’s not possible to know which is the correct one. So, you must cross your fingers and press one of the answers…
Perhaps a way to correct this is that both answers cannot appear in the same question…?
I understand each language has its idiosyncrasy, and it’s hard to avoid this kind of problems. Is it possible to correct this one?
