I cant use the slow repeat on excercises to listen again more slowly
Please, sent a bug report to Duolingo's staff
The last five days, there were at least 50 other users, who reported the same problem in the forums.
I'm having the same issue, but I thought it was their way of making me up my game. Now I'm thinking a glitch has developed. I'll shut down completely and restart to see if it corrects.
