I've downloaded the new app onto both my iPhone 3GS and iPad 2. The writing on both works beautifully. On my phone, each "flash card" plays a sound file for the word/character after writing it. On my iPad, it won't play the sound file even if I tap the icon for it. I checked the app settings and my iPad settings (other apps are making sounds as expected). I tried deleting and re-downloading the app, but that didn't fix it, either. Has anyone else had this issue?
