The new flashcards don't work right on my IPad. The old ones worked fine, but now only old school linear will work. And even with that there is no longer a voice that tells how to pronounce each word or phrase. Random and super random also have no spoken words and the whole thing freezes after about 3 or 4 phrases. How do I fix this...or how will you fix it at Fluenz.. It's very frustrating and is hindering my learning experience.
