Hello! I began embedding my daily slides into Canvas using the plug-in tool and choosing Google Apps. I then select the file. The first time I did this, I was required to log in to authorize the connection to Google. I did and I can see the slides. Unfortunately, about 50% of my students cannot. Canvas asks them to authorize but the process doesn't work and they either get an "authentication failed" or contact the manager of the Google Drive message.
I am confused. My students are logged into their Google Drive with the same email they use for Canvas. Google Drive is a registered service under in their account settings. Is there another step that they need to take in their Google account? Any advice would be greatly appreciated.
