I have created a class code and have tried to get 17 students to sign in with their Microsoft accounts. It only allowed 6 students to sign in, the rest received an error stating this class cannot be accessed because your teacher does not have enough seats. I most definitely have enough seats, as you cannot have less than 50 to start. I have also changed the class code and they have tried both Google and Microsoft accounts to no avail.
How do I get them started?
