We built out a new CTA to advertise an upcoming webinar along with a regular embedded form on a landing page. We have a workflow that triggers on form submission for a specific form on a specific page. Unfortunately, there is no option to enroll contacts in a workflow based off a NEW CTA form submission. The workflows still show the "Calls-to-action" (Legacy) marketing interaction.
Right now we'll have to consider if we can use the CTA at all if we can't trigger the enrollment in the 3rd party webinar program.
