iphone: turning off microphone
Just noticed something this morning - minor 'bug' only:
Generally, I leave the microphone enabled - but as I also do lessons on the commute to work, I also need to turn it off for some lessons.
What I noticed, though, is that when one of the microphone exercises comes up and I hit the 'turn off the microphone', Duolingo considers that a 'correct' answer (i.e. the progress bar proceeds to the next exercise).
I would expect that if I opt out of using the mike, that it would just replace the exercise and not count it as 'completed'...
