Is it still possible to enable authenticated (no-quota) push notifications for company app on Windows Phone?
There were a couple of blog posts by Windows Phone team documenting the process to enable no-quota push notifications for company app but now, on development portal, it is not possible to upload a certificate without linking it to an app.
I'm sure Microsoft added this feature a couple of years ago but now it seems to has been removed.
Do you know if authenticated push notifications for company app is still supported by Microsoft?
