AdobeMobileSDK 4.18.7 use with iOS

When I upload an iOS app that uses AdobeMobileSDK 4.18.7 I receive the following warning from Apple in an email:

Dear Developer,

We identified one or more issues with a recent delivery for your app, "xxxxxx" 6.0.0 (1). Your delivery was successful, but you may wish to correct the following issues in your next delivery:

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 use Xcode or Application Loader to upload a new binary to App Store Connect.

Best regards,

The App Store Team

When I use a hex editor on file libAdobeMobile.a I see references to UIWebView and UIWebViewDelegate in the static link library.

If I remove the AdobeMobileSDK cocoa pod from my project and re-submit the app to Apple I do not receive this email.  Our code only uses WKWebView.

Is this issue something that is being looked into?  This started happening on submissions on Aug 26, 2019 and later

Thanks
