Owner Signin Required for Doc Shared to User
One of my users has shared a Google Doc with several people in our company, giving them editor access. For most, the sharing worked as it should, but for one person it did not. When she clicks on the "open" link in the notification email, she is asked to sign in as the owner. And, of course, she can't do that. Screenshot attached in comment.
Context: The affected user is the admin aide of the document owner. She has delegated access to the owner's email (but cannot sign in to Google using the owner's credentials), reciprocal photos sharing, and access to a top-level folder in the owner's Google Drive in which the owner puts most, but not all, of her documents (sometimes within subfolders).
I have no idea why the admin aide cannot open the doc when it is shared with her in regular fashion. She is able to open docs without issue when they are shared with her by others, but she really needs to be able to open docs shared by her supervisor.
Any ideas will be greatly appreciated. (I am one of the Workspace admins for the company, if that helps with suggestions.)
