Hello! A co-worker of mine gets this error message when trying to download Catia. He is already added as a leader and owner in out collaborative space, but when I look for his name in the members list, I cant seem to find his name, but as we can see, several members are grayed out, so maybe he is one of the? What does it mean that several members (see picture) are greyed out without a name or a profile symbol?
