No matter what I do I cannot send any firebase notification to any token. I am always receiving this message.
Although the token is syntactically correct, it is not known to the Firebase
project you are using. This could have the following reasons:
- The token has been unregistered from the project. This can happen when a user
has logged out from the application on the given client, or if they have
uninstalled or re-installed the application.
- The token has been registered to a different Firebase project than the project
you are using to send the message. A common reason for this is when you work
with different application environments and are sending a message from one
environment to a device in another environment.

Please solve it I am sooo confused.
