The Duolingo powers that be decided to get rid of the flashcards. They would prefer you to use their Tinycards product now.
There used to be a flashcards function through the Words tab on the desktop site of Duolingo, where you could review words you had learned in your language lessons by way of flashcards.
Your account probably hasn't been transferred over to the "new" (rewritten) website yet. It will happen sooner or later, but in the meantime, enjoy the "old" website, because a lot things have been taken away in the new version.
