FirebasePushNotification plugin iOS - token not refreshing

Question

I am using the FirebasePushNotification plugin, and in iOS i have always issues.
In debug mode it works ok, but in release it never fires the OnTokenRefresh event (i know because i set messages boxes and I also print it on the screen).

What could be the cause of this? I am so frustrated, I've tried everything, just not working in Release mode.

Thank you!

Answer 1

So I finally got it to work!

I upgraded the plugin to the latest version, and also installed these in the iOS project manually:

• Xamarin.Firebase.iOS.CloudMessaging
• Xamarin.Firebase.iOS.Core
• Xamarin.Firebase.iOS.InstanceID

Then, I reuploaded the APNs certificate in Firebase. The Auth APN Key file is recommended, however it only started to work when I chose the other option and uploaded the APN certificate.

Thanks for the help.

@Cole Xia (Shanghai Wicresoft Co,.Ltd.) I downgraded the plugin and i was able to get the token.
However, the iOS app does not receive them.

I sent a notification thru Postman and it completed successfully:

   {  
       "multicast_id": 4267051523857827808,  
       "success": 1,  
       "failure": 0,  
       "canonical_ids": 0,  
       "results": [  
           {  
               "message_id": "0:1612045674651933%9166abc09166abc0"  
           }  
       ]  
   }  

But the app did not fire the received notification event.
On the other hand, in the output window I got this log:

[Firebase/Messaging][I-FCM002019] FIRMessaging received data-message, but FIRMessagingDelegate's-messaging:didReceiveMessage: not implemented

But i did implement that method as per instructions:

   // To receive notifications in foregroung on iOS 9 and below.  
           // To receive notifications in background in any iOS version  
           public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)  
           {  
               // If you are receiving a notification message while your app is in the background,  
               // this callback will not be fired 'till the user taps on the notification launching the application.  
     
               // If you disable method swizzling, you'll need to call this method.   
               // This lets FCM track message delivery and analytics, which is performed  
               // automatically with method swizzling enabled.  
               FirebasePushNotificationManager.DidReceiveMessage(userInfo);  
               // Do your magic to handle the notification data  
               System.Console.WriteLine(userInfo);  
     
               completionHandler(UIBackgroundFetchResult.NewData);  
           }  

I really do not understand what to do to make this work...
