App Tracking Transparency, or ATT for short, is Apple's opt-in privacy framework that requires all iOS apps to ask users for permission to share their data. This is done in the form of a popup where users can either consent or deny tracking.
To enable ATT in your app
Enter a descriptive text that will be displayed on the ATT dialog in your Admob node's att_textfield.
Handle Admob node's tracking_authorization_granted and tracking_authorization_denied signals.
If the user initially rejects the tracking request, then later on you can check if the user changed their mind and allow them to update their settings by opening the system app settings using the Admob node's open_app_settings() method.
