I implemented push notification in my app and it is working when i install build from xcode but not working when i install app via a link generated by diawi.com why this is
Push apns certificates are different for Development & production
if you install from xcode - It uses development certificate
if install from diawi.com - It uses production certificate
on parse,com i think you have uploaded .p12 file generated from development certificate.
you have to upload .p12 file of production certificate & then check.
