I tried to follow Microsoft Azure's guide to setup Push Notification with Android. But at step 4 I am stucked, as I can not find any places to enable the API for Push Notification, as the link leads to Firebase Cloud Messaging, which I can not use, since I need to provide my app for Windows too.
Azure requires GCM, but when I set it up using GCM, it fails with errorcode 401. What can I do?
