Splash screen not appearing

I can see AppMySite's splash screen when I test my app through the demo app. Why can't I see the splash screen I designed?

AppMySite enables you to test your app via our demo apps. While testing your app, you will see AppMySite’s splash screen and not the one you designed for your app. You cannot preview your splash screen on the demo app as it is associated with AppMySite.

Here’s how you can fully preview your app on Android and iOS devices, including the splash screen –

Android

Generate an APK build of your app and install it on your Android device. You would be able to preview your splash screen, along with every other screen in your app.

iOS

Install TestFlight on your iOS device. Once you install your iOS app within TestFlight, you’ll be able to fully preview your app’s splash screen.

While previewing your app’s splash screen is not possible with the demo, you can do this via your APK file and TestFlight.
