Hello. Thanks to you, I was able to make it using the App Inventor on our homepage. I was happy to sign up for Google Play last week, but I was rejected for violating my policy due to YouTube's background play. When I checked, I was able to see that the YouTube video in the homepage plays through the app, unlike when I watch YouTube videos on my browser, even if the screen on my phone is turned off.
How should I solve this problem?
