As the title says, the Export button, which was next to the flashcards button, has vanished. It was there 2 days ago. Uninstalled the software, reinstalled, rebooted etc. It's still not there. And the flashcards button is no longer functional.
I need to know whether the problem is at my end, or whether Amazon have made some sort of update within the last 48 hours. If the latter, it could either be a bug or intentional.
