react native firebase - Push notification iOS sometimes not working [closed]

I am struggling with sending Push Notification using the react-native-firebase.

There are somethings strange. Sometimes, the iOS app work perfectly, but sometimes, it receives the Push Notification ONLY in onMessage, which is terribly wrong.

I am using:

• React-native: 0.61.5
• React-native-firebase: 5.6.0
• Latest version of Firebase/Core and Firebase/Messaging
• Push Notification (added for both debug and release)
• Remote Notifications (added)

Please help me guys if you faced this issue before.

Below is the response message from Firebase when it come to onMessage function:

_messageListener
{"_collapseKey":"always_is_app_bundle_id","_data":{},"_from":"595939737681","_messageId":"-M26mNVZo-WhP5ev8dDN","_ttl":3600}

Many thanks!
