I'm working on an EPUB3, and the Table of Contents (the toc.xhtml file) shows in iBooks for iPhone & iPad, but will not link to the proper chapters. The file functions on other devices and other readers & validates perfectly, but I cannot figure out why the ibooks TOC will not function properly. I've scoured the iBooks Asset Guide, but have built the file according to specifications as far as I can see, so have not been able to come up with a solution.
Has anyone come across this before and/or have any ideas for fixes? I've tried the extra apple namespace, and tinkering with the file path in the href, removing the ol class...
Alternatively is there a way to force iBooks to read the .ncx file instead of the .xhtml as it's not functioning properly?
