I’ve recently exported this year’s version of a project I’ve been doing for a few years and I’m having some unexpected issues. I’m using Hype-made ads in InDesign, exporting to EPUB (Fixed Layout) and submitting to the iBooks Store. I’ve done this for the past few years without any problems. This year, I’ve done my standard hacks to workaround InDesign’s issues, and I’ve got an EPUB that looks great on the Mac and works well. On my client’s iPad with iOS9.3.5 it’s mostly OK. On an iPad mini (3) and iPad Air 2 running iOS 10, it crashes when I zoom in on the ads. Worse, though nobody found any issues last year, it’s crashing on last year’s edition, leading me to suspect a problem with iOS 10’s version of iBooks.
Has anyone else encountered any issues with iBooks crashing on an iPad, especially with the recent OS?
