Someone has emailed a shared link to a folder with me. I am able to click the link and view the items in the folder. I need to edit one of the documents in the folder. However, it only gives me the option to Direct Download or Save to My Dropbox. Even if I save it, changes that I make in the file are not updated in the orginal folder from the link. Is there something that I am not doing correctly or is the link not shared with editing capabilities?
