How do you report an error after a timed exercise?
Hi in one of the exercises, my answer was marked wrong. The word in question was competition, and I put concurso, which means competition, but I was marked wrong because I didn't put competencia. I didn't report the error during the exercise because the exercise was timed, but I couldn't report it after the whole set of problems was finished, so how do you report errors in that case?
There's no "easy" way to do this, unfortunately. If you remember the question, you can do another "untimed" review on the particular lesson where the word appears and hope the same question appears again.
The best way to do this is probably to use this userscript by Duolingo user HodofHod. It allows you to cycle through the questions after answering all of them and report any issues when the lesson is over. It's not an "official" solution though.
