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?

The correct answer is App Re-engagement because your goal is to encourage existing users to return to your app and try the new "30 minutes or less" premium feature. An App Re-engagement campaign is specifically designed to target current users who have the app installed but may not be actively using it, driving them back to take action. App Installs focus on acquiring new users, Website Traffic drives clicks to a website, and Video Views optimize for watching content, none of which directly prompt existing users to re-engage with your app.
