Android Studio: Firebase Push Notifications not working when app is minimized or closed

After updating compileSdkVersion from 30->31 in gradle file, android phones have stopped receiving notifications when the app is minimized or closed.

Gradle File:

implementation 'com.google.firebase:firebase-analytics:17.2.2'
implementation 'com.google.firebase:firebase-auth:19.2.0'
implementation 'com.google.firebase:firebase-firestore:21.4.0'
implementation 'com.google.firebase:firebase-messaging:20.1.0'
implementation 'com.google.firebase:firebase-analytics:17.2.2'
implementation 'com.google.android.gms:play-services-location:18.0.0'

Manifest File:

<service android:name=".service.ABCMessaging" android:exported="true">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

Error message:

E/AndroidRuntime: FATAL EXCEPTION: Firebase-AbcMessaging
    Process: <>, PID: 29537
    java.lang.IllegalArgumentException: <>: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

Can someone please provide any pointers?

    You need to set FLAG_IMMUTABLE or FLAG_MUTABLE in your PendingIntent like below

        PendingIntent pendingIntent = PendingIntent.getActivity(context, requestCode, notificationIntent, FLAG_IMMUTABLE);

    Try adding this dependency in the gradle:

    implementation 'androidx.work:work-runtime:2.7.0-alpha05'

    Also, as TomInCode mentioned, update the Firebase dependencies to the latest version.
