Two users reported a bug to me that is present in both Anki 2.1.66 and also at least in 23.10 Beta 3.
The bug consists of 1) the answer-side of the card being shown right away when a card is displayed, without clicking “Show answer”. Example:
When the user clicks “Show answer” he is taken to the next card (rating for the previous one unclear).
And 2) the “rate your answer”-buttons being shown even though the answer-side of the card has not been displayed. Example:
The examples I received seemed to happen with my somewhat JavaScript-heavy notetypes. Prior to Anki 2.1.66 I never received any reports like this.
The problem doesn’t seem to happen every time but only once every few cards.
One user was running Windows 11 Home. That’s the info I have so far.
Some demo decks if you want to try to replicate the issue on your end.
