When conditional logic is applied to a form used in the calendar booking section, the booking flow switches to the Form's redirect settings and no longer honors the Booking Calendar's default redirect.
Our use case: we want to disqualify certain contacts from booking based on how they answer a field in the booking form — a conditional booking form. But we also need the calendar's default redirect intact, since that's what sends qualified bookers to our standard "Call Booked" confirmation page.
Right now it's one or the other. Conditional logic and the calendar's native redirect should work together, or the calendar redirect should take precedence when a form is attached to a calendar.
