I've created a reflowable epub 3.0 in InDesign that exports great and seems to be working across all the various platforms.
The only oddity is the navigation menu display in ibooks (because it appears to display fine in the other formats). In ibooks, the Table of Contents hierarchy displays perfectly on the page, but the nav menu at the left isn't indenting/understanding the splits correctly. I've got all my styles assigned to the appropriate h tags in the TOC export menu, but, for example, Section 5.5 and Chapter 8 shouldn't line up. Again, this problems seems only to happen in ibooks. Wondering if there's a fix?
