Okay, so this should be a shared link that they can access. Currently, the shared links would allow you to view the modification date of the file, meaning if it was newly uploaded or changed, they would see this date on the site. It isn't possible to change or hide this date.
Hi @Mediterranean Arts, thanks for bringing this to our attention.
Did you create a shared link to a folder, or a shared folder that is added to an account?
This will help me to assist further!
There isn't really a way to do so, since modification dates are always visible on the Dropbox site.
