Hi @iowilliam
Not sure if you have the right keys. Are you inside the “Project Settings -> Cloud Messaging”? There you should have only one server key (the long one, not the “old serverkey”) and one Sender-ID.
The URL to this specific settings page should be something like this:
https://console.firebase.google.com/u/0/project/{project_ID}/settings/cloudmessaging/
Where {project_ID} is your project ID.
There is no need to add the “add Firebase to your webapp” snippet to your code.
Kind regards,
Nico
