I just recently went back to update my plugin adding in the newer version and the key and my pages from a popular book on my site looks like this: https://randomnestfamily.org/3d-flip-book/family-bible-study-reading-plan/ . The thumbnail image or page cover keeps appearing on every page, I had my website person clear all caches. What do I do next?
p.s. it also says "Please wait! The book is processing..." it never goes away.
previously this was an issue https://3dflipbook.net/question?id=1957
