I am using your B4J non-ui sending tool.
There is nothing in the logs.
It sends OK, but no notification in B4I.
It was working before updating the 3 files.
Sub Application_PushToken (Success As Boolean, Token() As Byte)
Log($"PushToken: ${Success}"$)
Log(LastException)
End Sub
And:
B4X:
Private Sub fm_FCMConnected
Log("FCMConnected")
'here we can subscribe and unsubscribe from topics
fm.SubscribeToTopic("ios_general") 'add ios_ prefix to all topics
End Sub
Are you sending the message when the app is in the background?
This was my iOS app configuration in Firebase console:
After the april 2020 update I did not receive notifications anymore.
So I decided to go for the APN auth key instead.
Go to your Apple developer account and create a P8 file.
You just have 1 key for all your Apps and it can only be downloaded 1 time, so save it in a place where you can find it again.
Then upload it to Firebase:
