Updated question :
Is it possible to sync the state of each Anki deck across multiple devices? For instance, if a user studies Deck A on their desktop and then studies Deck B on their mobile phone, can they sync the state of Deck A to their mobile device and the state of Deck B to their desktop?
Original question :
When I sync, should my study history (i.e. the decks that I have studied) be the same in Anki Desktop & Anki Mobile iPhone? If so they currently are not in sync in this manner. Thanks to anyone who can clue me in on this question.
