Not sure what I am doing wrong here. Message has both a subject and a body. Message was created in the Firebase console.
B4X:
Sub fm_MessageArrived (Message As RemoteMessage)
    Log("DEBUG")
    
    Log("Message arrived")
    Log("From: " & Message.From)
    Log("ID  : " & Message.MessageId)
    Log("Message:  " & Message)
    Log("Time: " & DateTime.Time(Message.SentTime))
    ''Log($"Message data: ID ${Message.MessageId}, Data ${Message.GetData}"$)
    
    Dim MMap As Map = Message.GetData
    ''MMap.Initialize
    Log("mMap.Size = " & MMap.Size)
    ''map = CreateMap("body1":Message.GetData,"title1":Message.GetData)
    For Each key As String In MMap.Keys
        Log("key = " & key)
        Dim value As Int = MMap.Get(key)
        Log("value =  "  & value)
    Next
    
'    Dim n As Notification
'    n.Initialize
'    n.Icon = "icon"
'    n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), Main)
'    n.Notify(1)
End Sub

Log:
B4X:
** Receiver (firebasemessaging) OnReceive **
** Service (firebasemessaging) Start **
FirebaseMessaging - Service_Start

The problem is creating the message in the firebase console.

To get it to work you need to use the Additional options like this:
