Not receiving DeviceToken on Release mode

[nk-alex]

I'm using .net8.0-android for this.

This is my setup:

.cproj

	<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
		<GoogleServicesJson Include="Platforms\Android\PushNotifications\google-services.json" />
		<PackageReference Include="Plugin.Firebase" Version="3.1.3" />
	</ItemGroup>

AndroidManifest.xml

<application android:allowBackup="false" android:fullBackupContent="false" android:supportsRtl="true" android:label="MyApp" android:icon="@mipmap/ic_launcher">
	<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
	<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
		<intent-filter>
			<action android:name="com.google.android.c2dm.intent.RECEIVE" />
			<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
			<category android:name="io.myapp.com" />
		</intent-filter>
	</receiver>
</application>

Service

[Service(Exported = false)]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class MyFirebaseMessagingService : FirebaseMessagingService
{
	public override void OnNewToken(string p0)
	{
		var deviceToken = p0;
	}
}

This setup is working on Debug mode. But when I compile using Release mode, OnNewToken never gets called. Even if I uninstall & reinstall my application.

By searching the internet I found out I had to add my SHA-1 release certificate to my firebase console (which I did) and download the updated google-services.json.

But that doesn't solve my issue either. What am I missing?
