Hi, I am using flutter. Within my flutter app, I have a WebView, and I am already rendering the PayPal buttons in it successfully :). Find out more about the plugin I am using here: webview_flutter The plugin uses WKWebView for iOS, and WebView for Android. Please also check out my StackOverflow question I have asked here - it also contains screenshots: https://stackoverflow.com/questions/57390362/flutter-integrate-paypal-buttons-with-webview It seems that the PayPal secure checkout fails on the last step of subscriptions. All I see after pressing "Agree and Subscribe" is a "Processing" screen on iOS, and a bank page on Android. This occurs right before the checkout finishes and calls "onApprove" - however - "onApprove" is never called! Any assistance will be greatly appreciated!
