When I first uploaded my cover, it appeared fine on the screen. However, after the book went live, I discovered that the jpg I created had a section of white that made the cover crunched up. It looks bad. I've since fixed the jpg, but when I try to replace the current covere, the website won't allow me. Does anyone know how to replace a cover after the book is live? I've emailed the people at Pubit. I have received a response from them in the past, but it did take a week or so. I was hoping for a quicker fix.
