I’ve added Firebase Crashlytics dependencies to my Android application, and while the Firebase initialization seems to be working fine (e.g., FirebaseApp.initializeApp(this) is called in onCreate()), I am not seeing any crash reports on the Firebase Crashlytics dashboard, even after intentionally throwing a runtime error.

I have added the required dependencies and applied the Crashlytics plugin in the build.gradle file. The ProGuard rules for Crashlytics have also been configured. I tried force-sending logs using FirebaseCrashlytics.getInstance().sendUnsentReports(), but the dashboard remains inactive.

What could be the possible reasons for this, and how can I resolve the issue to ensure crash reports are sent and displayed properly in the Crashlytics dashboard?

build.gralde(:app)
plugins{
    alias(libs.plugins.android.application)
    alias(libs.plugins.jetbrains.kotlin.android)
    alias(libs.plugins.hilt)
    alias(libs.plugins.compose.compiler)
    alias(libs.plugins.firebase.crashlytics)
}
dependencies {
    implementation(libs.firebase.crashlytics)
}

build.gralde(:project)
plugins{
    alias(libs.plugins.android.application) apply false
    alias(libs.plugins.jetbrains.kotlin.android) apply false
    alias(libs.plugins.hilt) apply false
    alias(libs.plugins.compose.compiler) apply false
    alias(libs.plugins.firebase.crashlytics) apply false
}

    override fun onCreate() {
        super.onCreate()
        Timber.plant(Timber.DebugTree())

        KakaoSdk.init(this, getString(R.string.kakao_share_app_key))
        FirebaseApp.initializeApp(this)

        Thread.setDefaultUncaughtExceptionHandler { _, throwable ->
            Toast.makeText(this,"Error", Toast.LENGTH_SHORT).show()

          // dashboard is not showing !
            Firebase.crashlytics.recordException(throwable)  
            FirebaseCrashlytics.getInstance().log("APP CRASHED MANUALLY")
            FirebaseCrashlytics.getInstance().sendUnsentReports()
        }
    }
}

I expected the Firebase Crashlytics dashboard to be displayed.
