Hi there,

I already read the other threads regarding the authentication error.
I can't properly make a new key because your tutorial is outdated.
Google developed a new Cloud Messaging Service (Firebase Cloud Messaging / The old GCM for Android is outdated, too.

I can edit a key or create a new one but I have to restrict them to iOS or Android App - or to IP or URLs. The field can't be blank. Which is the proper one? What do I have to fill in?
Any help?

Thanks in advance
