I did not submit it anonymously. Tried three times now. At the end there is that Mickey Mouse splash screen and after that the formstr home page. Nothing stored locally. I even created an empty form to see if local storage needs to initialized somehow and resubmitted the quiz form. But only the form create by me is there then. I even cannot delete it. When I sync with my profile (whatever this will do) I do not see that form in "my forms", neither in drafts.
