I found a workaround for scaling a placeholder geometry after you’ve placed an asset in a Revit model, and then change its scale. Initially only the asset within Enscape’s render view automatically adjusts its scale. This leaves the placeholder geometry stuck at the incorrect scale in Revit. The way to fix this is you have to use the Project Browser to open “Familes,” scroll down to “Plantings” and then find the specific asset. Now delete it and reupload the asset from Enscape’s Asset Library. This time, the placeholder geometry will have updated itself.
