Q: Why do I have a different numbers of subscribers before and after sending push message?
A: The system removes the devices after sending push notifications message as soon as Push Notifications Provider rejects the push notification token.
This could happen for two reasons:
- The device token became invalid – the application was removed from the phone.
- The token was sent to the wrong gateway – for instance application is in the AppStore and the gateway has not been updated from Sandbox to Production.
