Hello and thank you.

I don't think that the problem is the fact that a user is logged in or not or that the page is bookmarked or not. This can't make any difference, as long as the link is visited. Of course i suppose that the component is active both for guests and registered logged in users.

Maybe the problem is due to the fact that by default an event is tracked once per day. Thus if a user has visited the link on a certain day, all subsequent requests won't be tracked as duplicates.
