Hi Christophe,
Thanks for your message.
But, in fact, I've just ended to trash the folio and re-created a new one.
And I tell you, it was not easy because I took several hours doing this...
Try to create the app again, WITH THE SAME CERTIFICATES AND MOBILE PROVISIONING PROFILES.
It worked.
It was not a certificate problem, it was an Adobe problem!
The files and InDesign documents are the same. Everything is the same.
The worst thing in all this is that DPS and Adobe process don't give us a tiny clue about what might be wrong.
Nothing... the only way is to wast hours and hours seeking in forums and trying to test all kind of things without know what's happening...
Nevertheless, and once again, thank you for your reply.
