Please send feedback as instructed on note. 

Can you share file for testing.

Is Dn able to open file when you exporting object or scene from Dn and importing it back into Dn as 3d object?

Ok. I tride inport scene that I was exporting before. Yes, it's worked, Dn opened file. But You have to understand that this is not a perfect solution for problem, becous I loose my environment light settings and position and camera bookmarks saves.
