I have clicked Share on Facebook button typed a post and no download. It just give me the popup over and over again. It seems the ebook is remaining locked. I am logged into the c-sharpcorner.com website and my facebook account I see many users have had the same problem and have requested the ebook to be sent to their email address. Am I doing something wrong?
