@welcome14 we need a bit more information to investigate:

1. Can you add @Keep to your class the implements INotificationServiceExtension?
   • This will make sure your class is not renamed or removed due to minification setting you may have on release
2. Do you get any errors in the logcat?
   • Enable OneSignal Verbose logging if you are not seeing any errors.
3. Can you try disabling all minification in your release build?
   • Progurd, R8, etc.

i have disable the minification, and it works!

buildTypes {
release {
minifyEnabled true
}
}

@welcome14 does adding @Keep to your class also solve the problem? As it is recommended to use minification in release builds.
