I miss the type in SPANISH every time!
I have no problem with this task, but I always miss in what language to type in! please make it red or something :)
Duolingo actually addressed this problem recently (I used to have the same problem when I started) ! When it wants you to keep a sentence in Spanish, they keep the box on the left. When they want it in English, they move the box to the right side of the screen. I just double checked in my daily practice as well as the lesson and it seems to work!
