Android App Bundle

Hello everyone Why is it that when I try to publish an app, Google Console gives me a warning that the APK file is not optimized and recommends using the Android App Bundle? I didn’t add any garbage or anything like that. Can I get rid of this message, or if I make a game for Android using Unreal Engine 4, I will always see this warning?

With UE 4.25 you can make .aab files ( App Bundles ) and the warning will go away. Using only APK it’s not a problem. Google will remove some files if you’ll use .aab and will install only needed files.
