Information about how Blender works
The edges can only be added on a real mesh and not on a calculated mesh. In other words, it will not work if the target face is a face calculated by a modifier. The most common error is the attempt to add edges on a cube that is a plane and solidify modifier. In this example, you have to apply the solidify to access to the face and be able to add edges.
