Which of the following best describes the audience of the Push enabled for App filter?

The audience of the Push enabled for App filter is best described by users with valid push tokens for the specific app. This is because a valid push token indicates that a user has opted into receiving notifications for that specific application. The filter specifically targets users who have engaged with the app enough to receive push notifications, ensuring that messages are delivered only to those who have actively expressed interest in staying connected.

This focus on valid push tokens ensures that notifications are sent to an audience likely to engage with the content, maximizing the effectiveness of the push messaging strategy. It allows for targeted communication that is relevant to the user, enhancing their experience and increasing the likelihood of interaction with the app.

Considering the other options, they either include broader groups without the necessary criteria for engagement or focus on unrelated aspects, such as notification permissions or user habits across multiple apps. The specificity of valid push tokens aligns directly with the definition of the audience for push notifications, making it the most accurate choice.
