Survey123 does not yet support location 'streaming'. You currently need to manually capture GPS locations as you move in the field. This is something we are interested in implementing in a future release. I encourage you to submit an enhancement request via https://support.esri.com. Your request can then be attached to the previous request for this functionality. This helps us assess demand for the enhancement and prioritize it accordingly.
I know it's officially not supported yet, I was hoping someone found a workaround. I am sure a lot of companies will appreciate this streaming functionality, and I will submit the enhancement.
Just letting you know that we now have a beta implementation of location streaming for geotrace and geoshape question types which allows the user to directly stream location updates to the line or polygon being created in the map question as they move around.
You can test out the latest 3.15 beta builds with this feature via the Early Adopter Community and the relevant documentation can be found here:
