It looks like Keap has updated the landing page builder, and it looks pretty good. The only problem I’m having is that when a customer fills out a web form that links to that a landing page, it isn’t passing the contact details and auto populating the fields.
Any way to make this happen? Do I need a hidden field like in a web form?
I am having the same issue. Would love an answer to this. I called support and I was told that this is the way Landing Pages are designed this way this way - without that functionality - intentionally and there is no plan to make it happen. 
It seems like they fixed it to a point. The information that is transferring for me is just First Name, Last Name, Email and Phone.
