I have recently purchases the $40 iPad app v2.0.80 (2000800.2) and have a lot of cards in a few decks I need to sync with my Mac v2.1.44 (which also has cards).
How can I sync both devices together without loosing any content?
I also can not login to the iPad to sync as I get an error “pls check internet connect…error sending request for url (): error trying to connect dns error……blah blah….
I have done a password reset and am can login to AnkiWeb and the Mac app, just not the iPad which has my most valuable content.
