ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs . See https://developer.apple.com/documentation/uikit/uiwebview for more information.

After you’ve corrected the issues, you can upload a new binary to App Store Connect.

Have you any suggest on how to resolve ?
Thanks

Thank you for the walkthrough and the repo. It really helped me set up PayPal. I just wanted to know if there is a way to upgrade to the V2 API since PayPal says the V1 is deprecated and will not accept credit cards.
