The fact that Wyze produces a tracking number means that the package label was produced thereby initiating a pickup order to the shipper, usually FedEx. The next scan that should happen is upon pickup by the carrier. The fact that there is no scan history between Wyze and the actual delivery places the responsibility onto the carrier, not Wyze.
