For Android you can also change the Scripting Backend from Mono to IL2CPP. Since Unity Android Mono backend does not support arm64 which is required on [Android Play Market](https://docs.unity3d.com/Manual/android-distribution-google-play.html). But to keep the development iterations faster, you can also keep Mono and only later jump to IL2CPP.

For Android, Target API Level should be 33 or higher for Google Play Store compliance.
