Does PushWoosh automatically check the APNS feedback service before sending push notifications to bad tokens/devices?
For each device that has not been reregistered, stop sending notifications. APNs monitors providers for their diligence in checking the feedback service and refraining from sending push notifications to nonexistent applications on devices.
If it does, do you give us an error response when we try to send to a device token that is no longer valid?
