sorry, but I can't find free pdf to test

Ok, What I can do is, can send you An IPA file that you can run on iPad. To run the iPA on your device you should have to send me your device UDID, so that I can add in developer portal and then you'll be able to run the app. And I'll provide the test account to purchase in-app and download it from Home Screen. And thats it you'll be able to see the magazine in "MIJIN EDITIES" Tab on the to navigation bar (3rd Tab).

sorry, but also with IPA I cannot debug the project.
I can correctly test links feature only with demo project and PDF file that creates problems.
