On canvas, there's a really nice way for canvas to notify you when grades are published, someone replies to a discussion board, assignments are due, etc. via text message in account settings in webcourses. However, when I try to register my cell number, the confirmation code that is suppose to be sent to my phone never comes. I've tried over and over again, but it doesn't work. I have been able to use this notification method before on the canvas dashboard (at a different college) and don't understand what's wrong. Also, it doesn't have the re-send confirmation code link either.
