For implementing notification on my app I have followed "Register your app for the Windows Store" in link
But when doing so I cant see Push Notification link under services. Services includes Xbox Live, Experimentation, Maps, product collections and purchases link only. What is the reason for it? How can I enable Push Notification link on Services?
The WNS/MPNS page is now under App Management tab.
However, the main part of the setup (retrieving the app secret key) is then under the Live services site link. This will lead you to your app's page on https://apps.dev.microsoft.com/ and you will be able to get the secret key and package SID there.
