This long-running problem is still unresolved. When we try to invite students to a course, the invitation email is not received. I know this is an intermittent problem - sometimes it works. Last time we had to add students manually and send them each a password. Is there any word on when this problem will be resolved, or is there a workaround?
As it stands, for a course starting Monday, I will have to email materials to my students, and in the longer term we will have to reconsider whether Canvas is viable for wholly online courses.
