Push notification

Hello,

I have an android app created using react. The app contains a wordpress web site and enable push notification on mobile device. A push notification is generated on device when an article is published.

The app works but, starting from a specific moment (maybe after a wordpress core upgrade), the push notifications doesn’t work anymore.

I didn’t develop the app and I’m noto an expert in mobile app developing but I have the source code of the package.

Someone can help me understanding and repair?

Furthermore I don’t know how to test the mobile app to verify the app behaviour in a virtual dev environmet.

Following the libraries used in the mobile app:

App.js:
import React, { useEffect, useState } from "react";
import {SafeAreaView, StyleSheet, View} from "react-native";
import messaging from "@react-native-firebase/messaging";
import analytics from "@react-native-firebase/analytics"
import { NativeBaseProvider } from "native-base/src/core/NativeBaseProvider";
import RNBootSplash from "react-native-bootsplash";
import AppWebView from "./components/AppWebView";
import {configureNotifs, LocalNotification} from "./notifications/LocalPushController";

LocalPushController.js:
import PushNotification, {Importance} from 'react-native-push-notification'
