L shaped surfaces get a triangle shaped surface detected preventing user to interact with the floor.

L shaped surfaces get a triangle shaped surface detected preventing user to interact with the floor.
This is very important to virtual content to be related to real world right now on center L shaped surface there is no table and contents gets floating in the air when I place them. Please resolve it unless it is going to be confusing and nonfunctional for users of our games.

 

This isn't something we can change. Those surfaces are determined by ARCore and ARKit, and both platforms say the boundary geometry is always a convex hull, whereas an L shape is concave.

The plane boundary points are the best convex estimate for the surface, and not meant to be a precise measurement of the physical surface's edges.
