I've been using collaborations successfully for several weeks now. Its a great place to have students work together. Over this past weekend they started emailing me they couldn't get in. I have double checked and all of the "blocked" students are listed as having access.
It tells them they need to contact the file owner/administrator. If I manually send them a share link they can get it but its not working via the Canvas integration.
Any ideas? This is a huge issue when they have to share lab data and work with it.
