Last week, due to a recent update to iOS 13, we migrated Cordova to use WKWebView instead of the default UIWebView, using cordova-plugin-wkwebview-engine.
After that, we are unable to see local pdf that the app downloads from server, and we instead see the screen that you can found attached.
This happens with every PDF file that we try to open. We tried aswell with a empty PDF file as the attached and the behaviour is the same. We haven't tested the Demo version, but in case it works, what we could do with that? How we could solve the issue? The app worked well before changing the webview
FYI we have the plugin in the last version available
