During my daily review session, the last 15-25 cards of the session are not shown. I can see the green total on the right counting down, along with the red total in the center. But as soon as I solve the final card of the red total, I get the message that my study session is over. The green total usually reads between 15 and 25 right before this happens.
I can’t figure out any pattern for the cards that get left behind for the following day, other than that they’re not the brand-new cards that I just started studying that day. Any cards left behind on a particular day get shown/studied the following day, but then a different set of 15-25 cards gets left behind. This has been happening for at least a few weeks, though I don’t know exactly when it started.
Things I have tried: re-downloading the entire database from Ankiweb; checking the database on the iPhone; checking the media on the iPhone; removing unused media on the iPhone.
Any help appreciated, thanks!
