Customers can't track YunExpress orders once they reach the US

The silent week is usually customs clearance and the handover to the local carrier, and part of it is just that the first US scans don't always feed back into YunExpress's own tracking straight away. Once it's handed over there's normally a separate last-mile tracking number. Sometimes it shows further down the YunExpress tracking page, sometimes only your supplier or their YunExpress agent can see it, so ask them to send it as soon as it exists. Multi-carrier tracking sites often pick up the last-mile leg on their own too. Bigger win for your ticket count: say on the product page and in the shipping email that tracking can go quiet for up to a week or so after arriving in the US. Most of those tickets are people worried the parcel is lost.
