Can Adobe support assist me? - Can't use any new versions of Dimension... UV issues.

As I've mentioned a few times, I still can't open older .DN files. I'm still forced to use 3.4.11.

Previous models and scenes - I can't open.

I've eliminated everything out, except the models/objects I'm using, and everything points to a similar issue that others have had with UVs. Notably, I have no issues whatsoever opening and accessing files and objects in ALL previous versions. Yes, I can export an object as an .OBJ file, but that flattens everything - from editable materials/ layers, to the decals placed. The same goes with Stager...

Perhaps I can send a file over. Someone can test in previous version and then see what's happening in newer versions of Dimension to solve this issue. It would most certainly be so very much appreciated. Suppot for more complex UVs put Dimension on the map vs. other 3D programs.

Without being able to edit and work within Dimension, decals, layers, materials (not forcing to flat/export out) - it's a significant step backwards... 

Standing by for any assistance!!
