Firebase Messaging statistics always shows "0"

[iamkinetic]

Describe the bug
I'm using this plugin to receive push notification inside a iOS and Android mobile app. It's working ok except for one thing: when I look a the firebase messaging stats, "received", "impressions" and "open count" are always at 0 even if the notifications are received and viewed on devices. Only the "sends" stats in updated.

Should this be working? Am I missing something to make this work? I can't find anything in the doc.

To Reproduce
Steps to reproduce the behavior:

1. Send notification to device through FCM.
2. Receive and click on notification on device.

Expected behavior
"Received", "Impressions" and "Open count" should be updated.

Smartphone (please complete the following information):
