I'm an instructor and require my students to watch Mix. I set the permission as "limited - Anyone with a link must sign-in to view". So students must sign-in before they can watch.
After a week or 2, I asked my students not in the visitor statistics. About 1/3rd of them claim that they watched it after signing in several days earlier.
This is not a single occurrence. All my mixes suffer the same issue. The students who are affected seem to be random. Am I doing something wrong?
