Hello!  
I developed a web app using React that renders the content of a custom player. When I run it in the **webOS\_TV\_24\_Simulator** , the app renders correctly.  
However, when I test it in the **LG webOS TV Emulator 5.0.0** , it does not render anything — only a black screen appears.

I’ve already set the app compatibility to **Chromium 38** , but that didn’t solve the issue. What could be causing this?

You can debug your app with the Chrome Inspector. Please refer to [Debug the app](https://webostv.developer.lge.com/develop/tools/webos-studio-dev-guide#debug-the-app). Thank you.
