iOS. Background listener not calling when send FCM Push Notification

[ObranS]

Have an issue in iOS app background state and FCM Push Notification.

Steps to reproduce:

• The backend sends FCM Push Notification.
• iOS receives Push Notifications. Alert appears.
• onBackground callback was not triggered.

Unfortunately, neither onBackground nor onMessage was not triggered.

Are there any additional parameters I have to provide for FCM to stimulate onBackground callback?

Received remote notification request 627E-B950 [ waking: 0, hasAlertContent: 1, hasSound: 1 hasBadge: 0 hasContentAvailable: 0 hasMutableContent: 1 pushType: Alert]
Remote notification request 627E-B950 can be modified: 1
Process delivery of push notification 627E-B950

Hello @ObranS, have you found a fix for this? On iOS we are sending the notification throuh APNs, but the background handler is still not called.
