Flashcards are still not renewing after two weeks. This is very annoying!
Perhaps you should retitle this - making the title your account name doesn't help solve the problem.
Does this sound like the same issue? https://www.duolingo.com/comment/8661198
If it's an a/b test, then there's not a whole lot that can be done besides waiting it out. In the meantime, you might be interested in the Duolingo-specific flashcard sets on Memrise and Quizlet.
