I have the pre fill option enabled on my forms but haven't had success in actually getting the lead information to transfer over. Has anyone found a better solution than recreating and redirecting landing pages? That seems like a lot of additional work.
There's actually a couple of places where this can be accidentally turned off. I would check not just the form settings, but also the landing page actions > form settings on the landing page itself and the admin section > landing pages > form prefill
Assuming you have set everything up properly per Kristen's instructions, as discussed above I think this largely depends on whether the user has previously been identified on your web site via a form fill and whether you are iframing your landing pages into an existing web site or not. Do you have any more detail on that?
Im also in the same boat. Did anyone figure out how to get this to work. Given the webform is iframed into a website, Munchkin code in website header, fields all set to prefill?
