Hi 

I have been working on a web map project where map accuracy is essential for legal purposes. At the end of my development, I discovered that the web map scale is inconsistent with ArcGIS Pro. 

What would be the best approach to tackle this problem?

The reason my web map was matching the map scale on ArcGIS Pro was because they are in different Spatial references. The web map is in arcgis web mercator and my ArcGIS Pro was set to my local coordinate system.

Change the spectialReference parameter in the map view will correct put the web map to the correct scale.
