I loved this app until now. They need to fix this question about Cinco, seis... As it never takes your answer and others have reported it as well. They have turned off comments about it so I cannot add my frustrations. I cannot go to any higher lessons because it keeps failing here and have reported it numerous times with zero response or correction. I've lost over 15 hearts as well. I'll have no other choice but to find another app and uninstall this one if there's no resolution.
