I made my first application that uses Firebase and it works fine. I resume the sources of this one and modifies some cosmetic element, changes the Package ID and the JSON file, of course with a new Firebase project and I do not receive any more notifications, I have this as error:
The sender ID does not match the registration token. Check the sender ID used in the getToken query.
Any idea?
