title: Unhandled promise rejection on SDK39 - SplashScreen
body: <p>I have migrated to SDK 39. Upon loading the react-native + expo project on production mode, expo throws the following yellow message:</p>
  <blockquote>
  <p>[Unhandled promise rejection: Error: No native splash screen
  registered for provided activity. Please configure your application's
  main Activity to call 'SplashScreen.show'</p>
  </blockquote>
  <p>I have completely no idea where this error may come from. I have tried to use <code>AppLoading</code> while the screens are rendering but it has no effect.</p>
  <p>I want to comprehend what is going on and, at least, find a way to ignore the error without compromising the app's work flow.</p>
