Please update your Firebase initialization process and set valid Firebase options (API key, Project ID, Application ID) when initializing Firebase.

  <p>I got an email about a week earlier that I should update my google_services.json File, which I have done 4-5 times. No Improvements. It had been working fine for around a year. Its been only 2-3 days since I am facing this issue in the app.</p>
  
  <p>Subsequently, Firebase Cloud Messaging and other firebase services are not working. I am not doing programmatic initialization (that is, using a FirebaseOptions object to provide these values), just the default initialization using <code>FirebaseApp.initializeApp(this);</code></p>
  
  <p>I have tried <a href="https://github.com/firebase/firebase-android-sdk/blob/master/firebase-installations/API_KEY_RESTRICTIONS.md" rel="noreferrer">https://github.com/firebase/firebase-android-sdk/blob/master/firebase-installations/API_KEY_RESTRICTIONS.md</a></p>
  
  <p>Thanks in Advance.</p>
