APK not optimized
Warning:
This APK includes unused features and codes that are sent to users. Your app would be smaller if you used the Android App Bundle. When the app is not optimized for the device's settings, the download and installation size is larger than necessary. Larger apps have lower installation rates and take up space on users' devices.
Resolution:
In order to automatically optimize the app for various device configurations, use the Android App Bundle or create multiple APKs.
