I have mutiple sites of which one is an overview website. I use experiments to a/b test whether people use the menu of the overview website to reach the other site (defined in sites and running well) or they use the link on the homepage of the overview website. It recognises the control and alternative page (shows one of them per session) but it doesnt count the visit to the page of the other site after clicking on either the link or using the menu. Is this a bug or something not possible yet?
