I used the ios-quickstart example in my iOS app.
When I send a push-notification to my device throught the firebase console, the first one is sent and marked as succes but never arrives.
Any notifications sent after the first one return the following response.
{
"multicast_id": 8642270861911984600,
"success": 0,
"failure": 1,
"canonical_ids": 0,
"results": [
{
"error": "NotRegistered"
}
]
}
So for some reason the FIRMessaging token becomes unregistered but I can't figure out why.
I have already tried without succes:
- Created a new certificate with apple developer console
- Removed and re-added all the code
- Enabled and Disabled method swizzling (
FirebaseAppDelegateProxyEnabled)
Edit:
To get the above respons I used PostMan with the FCM REST API.
Using the REST API has the same results, first push gives a normal response, any push after that gives the NotRegistered error
When using the console I get the following:
The app delegate is exactly the same as the quickstart-ios example except for putting the registerForPushNotifications: function, which is called in -application: didFinishLaunchingWithOptions::

Something else interesting I've found is that, while the apple notification permission alert is showing, I can send notifications and I see them arrive in my debug console.
After I accept notification permissions they no longer arrive...
