Thanks for the great plugin!
I'm not sure if I'm doing anything wrong. I've made a quiz with the option of unregistered users. I've deactivated the "execute quiz only once" option so that I can test.
I am only getting statistics for one anonymous user, even though I have taken the quiz many times anonymously (with different name and email). I have entered two custom fields for name and email, to keep track of users.
I am getting leaderboard results for all of them, but only statistics for one anonymous user.
Can anyone help?
