Which of the following features is **not** included in the Push enabled for App filter?

The feature that is not included in the Push enabled for App filter is related to users who have unsubscribed. When a user opts out of receiving push notifications, they are effectively excluded from any notifications sent to active users because the system recognizes that they do not wish to receive such communications.

The other features directly pertain to the technical requirements and state of the app and users that are essential for delivering push notifications. Valid foreground and background push token presence ensures that the device is capable of receiving notifications, while foreground push activation refers to the actual action of sending notifications to users who are actively engaged with the app. These features work collectively to ensure that notifications are sent to users who are likely to receive and interact with them, maintaining engagement and effective communication through the app.
