### Problem
I have problem when using FCM in iOS. When i run the code from XCode for the first time and fresh install app to the device, app starts receiving notification from Cloud Messaging Console and from my Python server without an issue. After i stop the code and run the app from the device, It stopped receiving any notification with following error below; If i delete the app and again re-install from Xcode, it starts receiving notification with new fcmToken, till i restart the app.
Received Error from Python Server;
