I created a survey in Survey123 Connect that includes a geopoint map. The default value in the XLS form is set to null. The map is conditional on another question, so there are some surveys where the respondents won't even see the map. I tested a few where I didn't even touch the map. Yet when I go into Data on Survey123, there is a point at 0,0 for my entry.
I would prefer if this wasn't the case and the entry just had no x,y coordinates associated with it. Is that possible?
