wkwebview

My app has stopped working since ios 13.3 upgrade. It is now failing to display the page in Webview. This is my code :- Dim xui As XUI File.Copy(File.DirAssets, la(Index,0) & ".pdf", File.DirDocuments, "page.pdf") WKWebView1.LoadUrl(xui.FileUri(File.DirDocuments, "page.pdf"))...

Hi there Ive noted the b4i posts about this however nothing seems to popup that shows where this is found for b4a? Can someone please point me to the right direction? Thanks
