I have several forms using form capture that was working fine. It is supposed to match and update Contacts and Leads. I had "Generate Leads without Matching" flag set to No, and it would update a lead if it matched and create a new one if there was no match. All of the sudden, now when the form is submitted it does not create or update the lead record at all. It still creates and updates the contact record, but not the lead.
To temporarily get around this, I have to set the "Generate Leads without Matching" flag to Yes. So now it creates a new lead every time a form is filled out, instead of just updating the existing record.
Was there an update? Did something change? Seems like a bug.
