I’m in the early lessons of German, and the audio is becoming inreasingly distorted. Is this happening in other languages?
Yes it has happened to me on the Polish course. Normally, though, it's after I have been signed on for at least a couple of hours and have moved on to another few sites and then I come back to Duolingo to do some more lessons. I have found the best way to make the voice distortion stop is for me to go into my electronic device's settings and clear my browser history. Unfortunately, you lose what xp you had acquired during that particular lesson.
