Hello @dashdashuser, welcome to the QuickSight community!
The documentation for this does seem confusing, but Address is not an available option for a Geospatial data type. If you had a field that referenced a specific home address, it will not work in one of the map visuals. The lowest granularity outside of using Lat and Long would be Postcode.
When it references place names, it mentions a city name, not a distinct location like a store or home. I hope this helps!
