iBooks Broken? Fonts no longer displaying correctly

Hi There,


I have been exporting ePubs just fine from indesign CC, and loading them onto my iOS devices to see them function perfectly.


Suddenly, this does not work.


None of my specified embedded fonts are working. They show up in Adobe Digital Editions, but as soon as you move it to an iOS device all the embedded fonts break. Even fonts I have used perfectly fine before. I have all the rights to these fonts, and I have checked inside the ePub to make sure they are all called correctly.


It seems to me that something has changed in the way that iBooks works; like it wants the fonts to be declared in a different way than they were before. The content.opf declares all the fonts correctly, and sets "specified fonts" to true as it should.


How can I get in touch with Apple about this? I can't find a way to get in contact without being directed here.


Thanks in advance.

Just to confirm, the exact same ePub will display fine on iBooks for Mac. But fonts don't display on iPad Pro or iphone 6S Plus.
I could just put it up for sale and try and download it from the App Store, but seems like a terrible way to debug and see if it works.

Sometrimes, Apple folks leave their address in this forum. You could look for one and ask him/her if he/she can do somethging to push it to the right person.
