I am receiving this message every time I try to generate this app:
I don't know what this means, I've changed the filename several times with no success, please help!
Can you take a screenshot of the export screen (which contains the app name, package ID, version, etc) and post it here? Most probably this has something to do with the package ID or version entered.
I've found the problem, some of the linked files from the epub3 I've imported to create the app, contained dashes in it's names. I discovered that using an epub checker. Renamed all the files and the situation was resolved, my app is not rejected anymore.
Thank you for your assistance.
