What Roles Are Necessary for Push Notification Channel Creation and Use?

Question

Are there any groups, users and/or role assignments currently needed to enable registrations for using a notification hub from a UWP app? I am currently getting 0x000006d9/EPT_S_NOT_REGISTERED when attempting to create a channel which I wasn't getting in the past. Eventually, the attempt times out and an exception is thrown.

I have been and I am currently using var channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync(); to establish the channel via the Microsoft.Azure.NotificationHubs NuGet.

@Marc George Thanks for reply! Could you please clarify where are you seeing that 0x000006d9/EPT_S_NOT_REGISTERED error?
It’s doesn't seems to be typical Notification Hub response.

As for the about portal and role assignments – currently Notification Hubs does not have AAD RBAC support. We just use the Access Policy connection strings. The string with “Listen” permission allows for registering devices with the hub and should be the one shipped with the application.

Hope that helps,

Thanks for asking question! If I have understood right, you want to send notifications to specific devices running Universal Windows Platform applications. As mentioned in this tutorial that the channel URI that's assigned by the Windows Notification Service (WNS) can change at any time and you should register for notifications frequently to avoid notification failures. This example registers for notification every time that the app starts.
For apps that you run frequently, say, more than once a day, you can probably skip registration to preserve bandwidth if less than a day has passed since the previous registration.
