Hello! Is there a maximum amount of cars that can be added to one deck? Whenever I get to 20 cards in one deck, they stop being available to learn. I can see them when I click browse, but they are not available to learn.
Your deck options are probably set to 20 new cards per day. So once you’ve learned 20 new cards, that’s it for today, and you’ll see the next 20 cards tomorrow.
You can increase the limit if you want to study more, but keep in mind that in a few days or weeks you’ll have a lot more reviews to do. 20 is generally a good new card limit, but it depends on what you’re studying.
