Hello!
I have made a lot of image occlusion cards using Anki mobile, but when I go to review them, it only comes up with one card when reviewing, but I know that multiple cards have been made when I browse through the deck. I have not had this issue when making image occlusion on desktop. I have checked my settings, and all the options for burying have been turned off.
After you study the one card, do the other cards show up as still available to study? This might be hard to see on AnkiMobile, but after you sync, you can see on desktop if the cards are buried.
Are you sure you’re checking the right Deck Options, for the subdeck those cards are actually in, not a parent deck? Double-check that your subdecks are assigned to the correct presets.
What do you have selected for the New card gather order and sort order? For this you need to check the Deck Options of the parent deck you click to study, because that will control the Display Options for the session.
