I too, experienced this problem but found the first issue to be a human interface problem. When I’ve drawn my map and gotten my dimensioning done, and before I actually scan, the displayed message “No wifi networks detected” is misleading and confusing. I kept thinking that something was wrong, not realizing that I had a couple more clicks before actual detection would begin only with my click on “Start Scan”.
After clicking my location and initiating the scan, the veil was lifted. My scan did not produce any errors, fortunately.
