## I can't see any notifications.

+ **No notifications configured in the account.**

  Verify that your notification configurations exist. From the navigation pane, choose **Notification configurations** to view a list of existing configurations in your account.
+ **Notification configuration error.**

  Verify that the status of your notification configuration is **Active**. From the navigation pane, choose **Notification configurations** to view a list of existing configurations in your account. You can check the status of your notification configurations by viewing the list. You can also choose a notification configuration to navigate to its details page. If the notification configuration shows an error, choose **Edit** on the **Notification Configuration** page to fix the issue.
+ **Event not matching expected pattern.**

  Verify that the created Event Rule matches the emitted AWS event. For more information, see [Events from AWS services](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-service-event.html) in the *Amazon EventBridge User Guide*.

+ **Permissions error** - Contact your account administrator to discuss your permissions. 
+ **System error** - Try to create the rule again.

## My advanced filters aren't reflected in the managed rule.

Managed rules only contain source and detail-type fields. Your advanced filtering is still applied by User Notifications. For more information, see [Amazon EventBridge managed rules in AWS User Notifications](ev-managed-rules.md).

## My notification isn't showing any details.

We're working with other AWS services to make sure User Notifications contain all relevant details. Your feedback helps us prioritize the notifications we should work on next. To send feedback, choose **Feedback** in the lower left menu of the [User Notifications console](https://console.aws.amazon.com/notifications/).
