Am I correct in understanding that if I don't include a geopoint type question (i.e Not included at all, not just hidden) in my survey design then the Survey123 mobile application will still try to obtain a default location for the survey from the device's location? See here: Tracking Surveys - help topic
If so, at what point does the Survey123 mobile application capture the device location? Is it at the point the survey is opened, marked as complete or submitted?
