I am having the same problem.I have an approved app live in the App Store and I need to update it. I have an email from App Store Connect from 4/27 that says you can still update apps until December 2020 even if it contains references to UIWebView, however my binaries keep getting rejected for ITMS-90809 so I am very confused and frustrated.Unless they allow the app updates as stated, the only way I can resolve this issue with my ionic 3 based app since it uses Branch deep linking that uses UIWebView, is to update my app to use ionic 4 since the latest version of Branch that has removed UIWebView references requires it, and that would be a major code refactor that I don't have time to try an work on right now.Here is the email message from App Store Connect on 4/27:ITMS-90809: Deprecated API Usage - Apple will no longer accept submissions of new apps that use UIWebView as of April 30, 2020 and app updates that use UIWebView as of December 2020. Instead, use WKWebView for improved security and reliability.
