“Outline”/Chapters won’t load – File Hub by imoreapps Review

I have several medical books along with other files. All is ok except it wont load the “outline” for the book chapters. I get the spinning icon. I need to access the chapters for my reading. Please fix in an update. I have iphone 8 plus with latest ios update so i don’t believe it’s my phone. Same thing happens with my 12 inch ipad pro. Thanks for the quick response. I’ll change the rating to 5 stars once it’s fixed. Thanks.
