I am quite new to GA4 and have a question regarding the difference between the closed & open funnels, as the data in GA4 seems to be not quite consistent to me. First two steps in my funnel are Session_Start and View_item. In the open funnel I have a lot of users, who apparently stepped in the second step. This seems to be very uplausible, as they actually all have to start the session on the website before. Any ideas why this can happen?
Also when I create 2 funnels: 1.open funnel with Session_start and View_item steps 2.funnel with only View_item step,
the number of users who viewed the item is slighltly diffent. Shouldn't it be the same?
Moreover, the number of users at the first step differs when new steps are added or taken out. Shouldn't it be also always the same?
