To Reproduce

Use Microsoft.Azure.NotificationHubs nuget package version 4.1.0.
Ensure hub namespace set to standard pricing
Send notification Microsoft.Azure.NotificationHubs.NotificationHubClient.SendFcmNativeNotificationAsync(string jsonPayload, IEnumerable<string> tags) or Microsoft.Azure.NotificationHubs.NotificationHubClient.SendNotificationAsync(Notification notification, IEnumerable<string> tags)
Save NotificationOutcome.NotificationId
Poll NotificationId Microsoft.Azure.NotificationHubs.NotificationHubClient.GetNotificationOutcomeDetailsAsync(string notificationId)

Code Snippet Add the code snippet that causes the issue.

public async Task GetOutcomeDetails()
{
    var credentials =  new HubCredentials(
        connectionString: [RedactedFullSharedNotificationHubConnectionString],
        hubName: "[RedactedHubName]"
    var hub = NotificationHubClient.CreateClientFromConnectionString(credentials.ConnectionString, credentials.HubName);
    var result = await hub.GetNotificationOutcomeDetailsAsync(notificationId);
}

Expected behavior Expected to get outcome details.

Screenshots

Setup (please complete the following information):

OS: Windows 10
IDE : Microsoft Visual Studio Enterprise 2022 (64-bit) - Version 17.7.4
'Microsoft.Azure.NotificationHubs' NuGet package - Version 4.1.0

Additional context Add any other context about the problem here.

In our production code we use a ASPNET Api endpoint to send notifications. Once sent we use the notification id from the outcome to enqueue a message for polling the notificationId outcome details in a QueueTrigger. Currently we have quite a few messages that end up in our poison queue due to this issue.
