+#### Workaround for "App Tracking Transparency not requestable on mount, starting at iOS 15.0" issue:
+
+On iOS 15.0+ requesting App Tracking Transparency does not seem to work on mount (see [#648](https://github.com/zoontek/react-native-permissions/issues/648)). We can work around this by listening for app state change, and then requesting it when the app becomes `'active'`:
+
+```js
+useEffect(() => {
+  const listener = AppState.addEventListener("change", (status) => {
+    if (Platform.OS === "ios" && status === "active") {
+      request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY)
+        .then((result) => console.log(result))
+        .catch((error) => console.log(error));
+    }
+  });
+
+  return listener.remove;
+}, []);
+```
