I apologize if this has been asked before. I recently had my students add me to their Unity accounts in order to utilize Unity Collaborate to turn work in. I had them do a real basic assignment and then share the assignment with me through Collaborate. I was able to see the assignments populate in my Unity Hub. When I selected one to open, nothing came through. I checked a couple of students and it was the same with all of them. What might cause this? What are some things that I need to look for in order to make sure I can see their projects on my computer?
