Received the following error message after uploading a fixed layout epub 3 to apple.
Unable to authenticate the package:
ERROR ITMS-6015: "xxx.epub: Option specified fonts is not a recognized display option for default platform or for platform *" at Book (MZItmspBookPackage)
ERROR ITMS-6015: "xxx.epub: auto is not a recognized value for display option open-to-spread on platform *" at Book (MZItmspBookPackage)
(Needless to say the file passes epubcheck verification.) I assume this is referring to the 'apple display options' file that is added to the META-INF file. And I assume it is because I should have put the value for 'open to spread' as "false" instead of 'auto'.
, and perhaps because I added the 'use specified fonts' line at the top instead of underneath the 'fixed layout' line.
Perhaps someone knows of another reason why the error message came.
before I submit the file again, I would like to try to make sure this will not happen again, perhaps someone has the time to check what I have below and let me know if there are any errors.
Greatly appreciated.
