So I have been uploading recordings of my class to Studio, and my students don't seem to have access to the videos? 

I tried going into MY LIBRARY, creating a collection and then sharing with each student by their email, but even if I type in their exact email address the system doesn't "find" the student. What is going on???

When I am in my Canvas course and I click the three dots the only options are delete or change the thumbnail. 

How do I get these videos to my students so they can watch and comment?
