Hi Vincent, you do not receive the notification if the message status is pending. If the system fails to send the message after x number of times, then the message status is changed to failed.
Can you verify the message is actually send or?
Update:
Whenever you configure your FCM you won’t be able to send messages (at least I don’t, you get a null pointer).
But when you add it then edit it and save it, then it works fine.
I’ll try to create a hotfix and upload it here.
