Is something wrong?
I just had the strangest things happen while doing my French lesson. On the listen and type part, there was NO audio voice or icon. I could scroll down and get the correct answer. Then when I started typing in my answers for the other questions, it right away went to green font and told me I had gotten the answer correct. I don't know if this is my computer or something going at with Duolingo.
It's not something wrong with duolingo nor with your computer. It's your internet conection that went crazy and affected Duo ... My conection was odd one day too and the same thing happened
