When I am on the Decks page and a learning card becomes due, the count doesn’t increase. If, however, I click on the deck, the overview page shows the correct count.
This is not a problem if I have some other cards to review because I will open the reviewer anyway. However, if I have reviewed all of my other cards, it is possible that I may not even know that a card has become due.
I didn’t realise that. Because I start creating new cards after completing my daily reviews, I always thought that I must have accidentally triggered the refresh of the page somehow.
But still, have you considered triggering a page refresh whenever a card becomes due rather than updating it periodically (push vs pull, basically)?
