I invoked the getNotificationSettingsWithCompletionHandler method of UNUserNotificationCenter on multiple test devices. After dismissing the notification permission request dialog (without explicit denial), the returned UNNotificationSettings object showed inconsistent authorizationStatus values across OS versions:
**iOS 18: Returns UNAuthorizationStatusNotDetermined
iOS 14.2:** Returns UNAuthorizationStatusDenied
Where can I find official Apple documentation explaining this behavioral discrepancy between system versions?
