title: Rate in app not working/showing up when run from TestFlight
body: <p>I am using this code to prompt a rate us in my app:</p>
  
  <pre><code>if #available(iOS 10.3, *) {
      SKStoreReviewController.requestReview()
  
  } else if let url = URL(string: "itms-apps://itunes.apple.com/app/" + "MyIdHere") {
      if #available(iOS 10, *) {
          UIApplication.shared.open(url, options: [:], completionHandler: nil)
  
      } else {
          UIApplication.shared.openURL(url)
      }
  }
  </code></pre>
  
  <p>On the simulator, the rate prompt comes up as planned, but I i run it using testflight, the rate does not come up at all. Any tips?</p>
