Dear all, I am Alberto Bertello, I have attended the DRUID conference in Copenhagen in 2021 and I would need Invoice and a certificate of attendance. Unfortunately, it seems that after the login I cannot access the page related to the conference 2021 and the related documents. Would it be possible to receive them via email? Thank you in advance Best Regards Alberto Bertello -- *Alberto Bertello, **Ph.D. in Business and Management* *Research Fellow* Department of Management School of Management and Economics,University of Turin Corso Unione Sovietica 218/bis 10134-Turin, Italy
