When I create a new sub-deck and have written out the cards. I often try and review the deck for the first time immediately. However, over the last two days, I have noticed that not all the new cards appear to be reviewed, not even when I extent the new card limit for the day (it suggests there are no new cards available). So at this point I assumed that the cards had, for some reason, been deleted. However, upon utilising the “Browse” tool, I discovered that the cards were, in fact, present in the deck, but I cannot access them to review. Any suggestions?
I’m afraid I have already consulted this page you have linked, it does not cover the issue I have highlighted.
