We tested the sample app on the same TV model, and it worked with no issues. To check the issue, it should be reproducible. Please make sure you are testing the original version of the sample app, as changes can cause issues. If the problem persists, please check with the Web Inspector. You can find more information in [Debug the web app](https://webostv.developer.lge.com/develop/tools/vsce-dev-guide#debug-the-web-app). Thank you.
