Form prefill not working

[Jamshaid]

I am wondering then where is the issue? Is anyone able to found a solution for that?

We have the same issue - link from email to profile page, and the form is not prefilled, but have been before.

We'll need more information. Is the link tracked (rewritten so it bounces off the tracking server before being redirected to the final destination link)? Can you establish that the destination link has the all-important mkt_tok query param?

And supply an example link (from a real email sent to a dummy lead -- not a sample email) please.
