[iOS] After 'IPA file', notification is not working

Hello guys.

I create a IPA file for ‘ad hoc’. That way beta testers can download.

Everything seems working fine but the notification is not working.

Once, user login, I get ‘registration id’ from ‘Phonegap-plugin-push’ plugin. I would send to server to send any notification.

This notification is working when I locally build an iOS app and install through Xcode.

However, This notification is not working when I create IPA and install this IPA through web browser.

Anybody has similar situation?
I have no idea where to start to debug.

Thank you.
