You're a food delivery service app,and you want to let your users know about a new"30 minutes or less"premium feature you're launching in your app.Which campaign objective should you choose?

App Re-engagement is the correct objective because it focuses on encouraging existing users to open and use your app again. Since your goal is to inform current users about a new in-app feature, this objective is perfectly aligned to drive them back into the app to discover and utilize the "30 minutes or less" premium service. Video Views would be suitable if the primary goal was simply to maximize views of a promotional video, not necessarily to drive in-app action. Website Traffic would direct users to a website, which is not the desired outcome when promoting an in-app feature.
