Why are my Push Notifications duplicated?
If there is consistent duplication for a particular device then it is likely that there is both a deviceId and clientId subscription for that device to the push channel. Removing one of these will prevent future duplication.
Note: DeviceId subscriptions will deliver push notifications to a singular device on that channel and clientId subscriptions will deliver push notifications to all devices with that clientId.
