HI all and I need help :)
Hi all. This is my first post!!!
I need some help with my epub files.
I convert one of my books from InDesign into epub and correct that with Sigil.
Then I validate it EPUB Validator. Everything is fine on my kindle. Then I convert that into mobi with Calibre, for my Android phone. I have Kindle reader app on my phone, but there are only squares displayed. What is the problem???
