small problem with push notification on iOS

I have app working on Android and iOS using Onesignal. The problem is that on iOS I can’t see message when app is in foreground. I do receive notification and can see the message when app is in background but when in foreground message is empty.

Same code is used on Android and iOS. I’m using latest Felgo. iOS is on iPhone 6 version 11.2.6

Below is debug from iOS and the Android, you can see that there is empty message on iOS (qml] Received notification)

IOS:

Code I’m using for Onesignal

OneSignal {
        id: onesignal
        objectName: "onesignal"
        logLevel: OneSignal.LogLevelVerbose
        appId: Constants.oneSignalAppId
        googleProjectNumber: Constants.oneSignalGoogleProjectNumber
        onNotificationReceived: {
            console.debug("Received notification:", message, JSON.stringify(additionalData), isActive)
            onesignalRect.msg=message
            showOnesignal(true)
            // Possible actions:
            // - Read message from data payload and display a user dialog
            // - Navigate to a specific screen
            // - ...
        }
        onTagsReceived: {
            var tagStr = ""
            for(var tag in tags)
                tagStr += tag + " = " +tags[tag]

            if(tagStr != "")
                tagStr = "Current tags: "+tagStr
            else
                tagStr = "Current tags: no tags set"

        }
        onUserIdChanged: {
            console.debug("Got OneSignal user id:", userId)
            AppData.setOnesignal(userId)
        }
    }

What can be the problem?

Best,
