[@nativescript/firebase-messaging-core][iOS] Notification token is regenerated after app is killed

Inizia in main.ts e segui firebase().messaging().registerDeviceForRemoteMessages() e getToken() durante l’inizializzazione. Riproduci il primo avvio di iOS e quelli successivi, verificando le versioni dei pacchetti in package.json e i due risultati dei token. Il lavoro è completato quando le notifiche funzionano al primo avvio e getToken() rimane stabile dopo la terminazione e il riavvio dell’app.

There is a weird behavior with our app about the notification token in iOS only.
We have search everywhere to find for a fix for this issue but we didn't find anything.
When I launch the first time the app, I get the notification token with firebase().messaging().getToken(), then we save the token in our user database and send notification from our server.
The first time the app is launch, the notification are not received, it only works after killing the app and relaunch it again.

But that's not it!
After the second launch, if I kill the app and then launch it again, the token change!!
firebase().messaging().getToken() is called twice, the first one return the old token and the second one return the new token
According to firebase documentation, the token only change if the app is uninstalled or data is reset which is not the case
