[🐛] FCM onMessage triggers when the app moves from background to foreground [iOS]

[aslihanturkdonmez]

Issue

When I send a notification while the app is in the background, the notification is received, and when I enter the app, onMessage is triggered, causing the notification to appear again. This works well on Android.

Javascript

useEffect(() => {
  const unsubscribe = messaging().onMessage(async (remoteMessage) => {
    Alert.alert("Hello");
  });

  return unsubscribe;
}, []);

Notification Content

{
  "token": "token",
  "data": {
    "notificationType": "xxx",
    "priority": "high",
    "id": "123435436",
    "actions": "[{\"title\" : \"test\",\"id\" : \"1\"}, {\"title\" : \"test2\",\"id\" : \"2\"}]",
    "title": "Test!",
    "body": "Test notification"
  },
  "notification": {
    "title": "Test!",
    "body": "Test notification"
  },
  "apns": {
    "payload": {
      "aps": {
        "content-available": 1,
        "mutable-content": 1,
        "sound": {
          "critical": true,
          "name": "default",
          "volume": 1.0
        }
      }
    }
  },
  "android": {
    "priority": "high"
  }
}

Have you converted to AndroidX?

Hello, I'm not reproducing on iOS, could you provide a full sample? Thanks

Same as #7836

This issue was related to my notification content. The problem was resolved when I removed "mutable-content": 1.
