Translation:Αυτοί πίνουν νερό.
What I have found happens quite often is that when you click for the audio to play, it does not play the whole phrase, but if you click again, it does. This happened to me just now, when I checked the audio on this page. So,
Is there a bug in the system?
I think so. Duolingo is optimised for Google Chrome (I can't find the reference right now), so if you are running an up-to-date Chrome version, and there are no other reasons why audio may be malfunctioning (see the Help article My sound is not working - What can I do), please file a bug report here https://support.duolingo.com/hc/en-us/requests/new.
I typed in Aυτοι πιvουv vερο and the app tells me the correct answer is Aυτοι πιvουv vερο and takes me in a loop to do it over. The problem is not the accents since the app has accepted all other responses without accents.My response and the 'correct' response are exactly the same. How do I get past this loop?
