I just tried to do progress quiz, but unfortunately it stoped in the middle, i just notification that Duolingo has problems at this moment and that's all. After few moments i purchesed other one, but same problem came again...
Now i have lost 50 lingots, is there any way to get them back, ksince i got that sign that Duolingo has problems on this moment??
I wish there was a way to review the test after it has been graded so we can see our mistakes. How will we learn otherwise?
I had the same thing happen when taking the Danish progress test:( I asked if I could have my lingots back via the support button on the left. I don't think there is much chance of getting it back though, but you could try.
