How to Enable Kotlin Android Extensions by Default in Android Studio 4.1
In this commit you can see the message:
Replaced kotlinx synthetic with findViewById
kotlinx.android.synthetic is no longer a recommended practice. Removing in favour of explicit findViewById.

Other alternatives:
findViewById- View Binding
In Kotlin 1.4.20-M2 JetBrains deprecated Kotlin Android Extensions compiler plugin.
