Unable to receive response from the VivaWallet App

I am trying to integrate Vivawallet in my ios app, but I am not able to receive a response back from VivaWallet on the outcome of the payment.

I am using the same app delegate code as the sample app:
`@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    print("Application start")
    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    print("Response URL\n:", url)
    guard let components = NSURLComponents(url: url, resolvingAgainstBaseURL: true),
        let path = components.path,
        let params = components.queryItems else {
            print("Invalid URL or path missing")
            return false
    }
    print("Path: \(path)\nComponents: \(params)")
    
    
    //MARK: - Do any additional actions after parsing the data
    return true
}

func performInterAppRequest(request: String){
    guard let url = URL(string: request) else { return } // url with constructed parameters
    UIApplication.shared.open(url) { (result) in
        print("InterApp Request URL:\n", url)
        if result {
            // The URL was delivered successfully!
        }
    }
}

}
`
I tested the app functionality both in my own app as well as in your sample app. In both cases I am able to send a payment request to the VivaWallet app, but in my own app I can never receive response back.

In your sample app, the second func application() is always called whenever I cancel the payment from the VivaWallet app and I see the response back. In my own app, after opening the VivaWallet app with performInterAppRequest, any action I perform on VivaWallet stays on the VivaWallet app and never sends response back to my own app.

Do you know what might be the problem?
