Which of the following statements about the Push enabled for App filter is true?

The statement that "It includes only users with valid foreground or background push tokens" is correct. This means that the filter is designed specifically to capture users who have the ability to receive push notifications, thus requiring them to have valid push tokens.

Valid push tokens indicate that the device is capable of receiving messages, whether in the foreground or background, which enhances engagement with your app. By focusing exclusively on users with these valid tokens, you can ensure that you are targeting an audience that is actually reachable through push notifications.

Other options do not accurately reflect the functionality of the Push enabled for App filter. For instance, suggesting that it does not consider push tokens would overlook the essential requirement that tokens are vital for push notification delivery. Similarly, the notion that it only includes users subscribed to both notification types misrepresents the inclusivity of the filter, as it does not require both types of notifications to be valid, just at least one. Lastly, claiming it is equivalent to just a Push Enabled filter does not take into account the nuances in what specific valid tokens mean in the context of app engagement.
