I have logged in to DRUID21 conference profile, but I can not see my old paper submission anywhere in my profile (see my profile below, it reads “Not yet open for submissions”). Would it be possible that somebody would just remove the PDF from there. We have now submitted the paper to a journal and they require us to have it removed before it can be sent out for review. Thank you for your help in advance.
