@stefan09 I can confirm that we have been approved for release several times after making this change. Our app does not use the AppTrackingTransparency popup at all, and we launch web URLs which contain cookies, however it is not within our app. Launching them in the user's browser does not require AppTrackingTransparency popups.
However, if you plan to keep the content "in your app" by using a webview, regardless of which type of webview you use, it seems that Apple will require you to display the AppTrackingTransparency popup to users.
