I launched a Facebook campaign, and after one day, Ads Manager shows 3 purchases. However, in reality, I haven’t received any sales. When I checked my Funnel analytic, it also shows 3 page visits on the upsell and thank you pages—this shouldn’t be possible since new customers shouldn’t reach these pages without making a purchase. Could this tracking error in Funnelish be causing Facebook to receive incorrect purchase data? And how can I fix this?
