The WebViewer component and related webView extensions now have the same issues as App Inventor:
PS: This issue ocures only on Android 9. The WebViewer collapses after a few ms. However, if something is triggered / executed on the screen, the WebViewer will be displayed correctly again. So if, for example, a fast clock (TimerInterval = 30) set eg a Lable (Lable.Text = empty string), it’s working again.
