I just got the following from Apple:Dear Developer,We identified one or more issues with a recent delivery for your app, Please correct the following issues, then upload again.ITMS-90809: Deprecated API Usage - New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview).Best regards,The App Store TeamI understand that this is deprecated for new apps in 4/2020 and for updated apps in 12/2020. This is NOT a new app.We have got this message many times before. New apps have to have this completed by April 2020, Updated Apps by December 2020.To us this is an updated App. It has been in Test Flight for over a year and we updated date it about every month. We use a different a unique app bundle for promotion to the App Store. I don't know why.The only thing I can see that we did differently was we needed a new provisioning profile. But that shouldn't mean it is a "new" app.What criteria does Apple use to indicate whether an app is "new" or "updated".This was just updating an app in Test Flight for testing. I think this is a mistake. We REALLY need to start testing the app. How can I ask Apple abou this?

Thank you. I do not know why our outsourced developers have multiple apps. I always wondered why. We have a version that is the production app and a version that is a development version, but we don't move the development version to production.
