Spent 3 weeks chasing why our demo form leads vanished from HubSpot
Our demo request form was sending leads into a black hole for 3 weeks before I figured out a privacy script on our site was blocking the tracking cookie on Safari. I went through maybe 40 test submissions and two calls with HubSpot support before a coworker in Austin suggested opening the browser console, where the block showed up in about 5 seconds. What is your go-to way to test that your forms actually pass lead source data through to the CRM?
