Has anyone else noticed since the new version of the desktop client was pushed out for Teams that "Copy link" permissions aren't working as they should?
Typically, "copy link" and "people with existing access can use this link" makes it easy to send out links to help people find documents. However, we have noticed lately this link doesn't work and adds extra sharing permissions to the file- the user will get prompted to log in with their email address and then get a message saying the file hasn't been shared with them. But if you highlight the URL within the Sharepoint site and copy and paste that link, sharing works. Any thoughts or has anyone else noticed this?
You appear to be on an early release tenant with the new files tab experience. I don't think this has started to roll out to production yet and thought this was a bug that had happened to Sharing in general awhile back (not in Teams but SharePoint / OneDrive). Curious if it's possible you have a regression of that.
