I am setting Mixpanel up, and I found out that if I log in with a user (and identify that user), log out and then re-register as a new user, the new user's details overwrite the previously logged in user (presumably when I call alias). How can I tell mixpanel that a user has logged out and to reset the identity token (make it anonymous again)?
It was released on Mixpanel Javascript version v2.8.0 the mixpanel.reset() function, so that's officially what should be called on user logout. See https://github.com/mixpanel/mixpanel-js/issues/67 .
