Why does the link in my email not work?

The parent notifications you are receiving are like a blind carbon copy email of your student's notification.  The link in the email takes you to the student login page, not the parent page.  Rather than clicking on the link, use this as a reminder to open your app or go to the district website to log in to Canvas.  You can also set your notifications to include the name of the student, along with the grade of the assignment in your account settings.  Canvas will not automatically include this information until you give them permission to due to privacy regulations.
