I use Anki on the Desktop version of the Windows application, Version 2.1.66 (70506aeb).
I have no problem creating cards and reviewing them in the same session. However, the next day, when I open a new Anki Desktop session, some of my cards are missing. I cannot find them in any of my decks, and I’m really confused because I always sync before I close a session.
Is this a bug? Any ideas?
