Hello Daniel,
The Site Map report should include the map scale, however, there currently seems to be an issue where the map scale is being mostly cutoff. The map scale should appear in the lower left corner of the map and it is now only partially shown.
Thank you for reporting this issue. We will work to resolve the problem as soon as possible. As a temporary work-around, you might try adding the site to the map and creating a PDF. The PDF includes the map scale.
We greatly appreciate your feedback and thank you for using Business Analyst!
Best regards,
Donna
