If you're having an issue with one of the Leanpub apps, please email hello@leanpub.com and let us know whether the issue is with the Leanpub app on a computer, iPhone or Android. Also, if possible, screenshots of the issue help us greatly.

Anyway, regardless of any app issues, the PDFs will work on computers (e.g. Preview, Adobe Reader, etc), the EPUB files will work in Apple Books and the MOBI will work on Kindle. So, if you're having an issue with any of the Leanpub apps, our recommendation is just to download the book files and use one of those...
