Some collegues and I have currently the problem on every Miro board that we can not collect an assignee for the kanban card or that I can not collect a free user/guest (which was possible before). I can just assign people with a licence for Kanban cards. The people with the licence can collect everyone (also me who does not have a licence). I am a little bit lost because before it was possible and not not anymore. Does any of you does know how to solve the problem? Thanks!
