Repetition - click on sound icon does not work
When selecting a word on https://www.duolingo.com/words and clicking on the sound icon, there's no sound in some cases.
And how does Duolingo check if a word was repetited?
Yes, but even if a sound will came out, will Duolingo record that I clicked successfully? It's true that it's good to repetite from time to time, but I really woudn't like to see degressed strength bar every day.
