What do we do when the Flashcards have mistakes?
For example, the Spanish flashcards provided the solution of both "comen" and "comemos" to be "eats", when it should be "(they/you plural) eat" and "(we) eat" respectively. There is no place to report it.
I gave up on the flashcards on Duolingo and went and built a deck on Anki. I could have dealt with the errors, but the program kept giving me the same set of cards, so to practice other words I would have to do multiple sets.
