I only followed App Tracking Transparency instruction - https://developer.apple.com/documentation/apptrackingtransparency and added NSUserTrackingUsageDescription in Info.plist Versions of testing iPhone6s iOS: 14.4 Xcode: 12.4 (12D4e)

Sorry, It may be my problem. I found that the Applications will only appear in Setting Privacy Tracking after user has made any decision on the permission request since notification permission works like it too

luigi0pl  I think the app would only appear in Privacy Tracking after the tracking alert has shown to user just like request notification
