Hi Shirley! Thanks for posting. When you are in the Shared With Me view those document thumbnails should have a gray circle on them with two "person" icons in it. Click on that and if you don't have sharing permissions for that document it will just show you a list of all the collaborators (including the owner at the top). If you do have sharing permissions for that document you may have to select the "advanced" button and then it will show you the list of collaborators. Hope this helps!
