Hi @DougBrowning,
In the UC presentation we mentioned adding support for tracking (similar to Tracker) in Survey123 in a future release in the road map, however this is different to streaming the geotrace/geoshape locations for the geometry of the feature using the map question.
The tracking capability will use the Tracker feature layer, similar to Field Maps, and we are currently working on implementing this in QuickCapture first, and then Survey123.
Regards,
Phil.
