Hi. We've created student groups on Office365 admin panel. And then when we want to send homework to a particular group of students, we can not see the group name on the list! We have email groups for each classroom like 1A, 1B... For example, i teach in multiple classes and i created a team and added my all students, then created channels for each class. And when i create an assignment and want to select group 1A or 2B for instance. Unfortunately i can not see that name of group on the list. What can we do?
