In a course with pending student invitation the 'Conclude' button is not shown. I assume this is because you cannot conclude a course with a pending invitation.
How can I, teacher or administrator, force all pending invitations to reject without masquerading as each student?
We have two manual classes that invite students. The owners of these courses did not want to all open enrollment. The students do not have to accept the invitation, and many do not accept, but most that don't accept do not actually go to Canvas to reject the invitation. This leaves many pending invitations.
