Why do we have to reset token during debug?

[azrinsani]

I'm going through a series of pain trying to get notifications to work. Currently it only works if the App is opened. If my App is closed, notification will not be received and worst off there are no logs to troubleshoot why such a thing happens.

Anyway, just my rant.

I'm confused why the need to reset token after debug run? I'm concerned if this is effecting the delivery of notifications to my App.

Particularly the code section is as follows:
FirebasePushNotificationManager.Initialize(this, true);
