The Survey Demographics report (which you'll find in Question Heat Maps) previously only contained data for feedback surveys. Whilst still mostly useful for that source, the report now also includes Mystery Visits and Delivery Audits at the request of some users - not for demographics such as age and gender, but for some of the other visit profiling measures. For example, it may be useful to see how scores for the whole report vary according to 'Reservation' (i.e. whether or not a person booked an eat-in visit). To see such data, you would need to have a relevant question tagged in your questionnaire (your Client Success Manager can help with this).
