Hi again.
I did more traceback of myself. I still have the old computer in my hands. I started it. Go into Chrome browser. Go into Designer project selection. There projects are listed, I can select. I export stuff to have it, (I found also that I had done so before, nice). I go into Edge, log in, no warning about cookies, I have bee into Stardog cloud with Edge before. Go to Designer project selection, it is empty. I have probably only used Explorer in Edge, demo stuff. Hence Stardog info about Designer project selection is in cookies only is right. Disturbing to me, bad design. Designer project selection should not be browser dependent, not friendly to users. Please remove such dependencies.
The question, in the previous post, about where models and mappings are stored still is open. The answer should be known to users.
Regards, Einar
