New iOS 14 StoreKit deprecate using as SKStoreReviewController.requestReview() Ok I create method to request feedback for iOS 14
func rateApp() {
        var ud = UserDefaults.standard.integer(forKey: "rew")
         NSLog("rew show count is %d", ud)
        if(ud >= 1)
        {
            
                if #available(iOS 14.0, *) {
                    if let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene  {
                    SKStoreReviewController.requestReview(in: scene)
                    NSLog("rateappios14")
                    }
                } else {
                    // Fallback on earlier versions
                    SKStoreReviewController.requestReview()
                    NSLog("rateappotherios")
                }
            
            
        }
        ud = ud + 1
        UserDefaults.standard.setValue(ud, forKey: "rew")
        UserDefaults.standard.synchronize()
    }
I tested it on device deployed from Xcode, and on simulator all is fine. But then I upload to App Store and download it, then review request not working completely. Also not works in TestFlight.
