_________are created automatically when you link your app events with Twitter through your mobile measurement provider.

Mobile tailored audiences are automatically generated when you integrate your app events with Twitter via your mobile measurement partner (MMP). This integration allows Twitter to receive real-time data about user actions within your app, such as installs, purchases, or sign-ups. Based on these events, Twitter automatically creates audience segments that you can then target with your ad campaigns. App Install ads are a campaign objective, not an automatically created audience. Custom metrics in Ads Manager are user-defined performance indicators, not audience segments.
