I'm having difficulty creating new flashcards for the newbie series past lesson 11 and for the absolute beginners series 1 past lesson 2.
I deleted some of my mastered decks and it still won't let me create new ones so I've ruled out that I saved too many.
I was able to recreate the decks I deleted as well. It seems to be for lessons 12, 13 and 14 that I've tried so far and absolute beginners 3-5.
I can still save words to my wordbank but the flashcard tool was really helpful in memorising my vocabulary.
