Sometimes the local postal service tracking will give additional information that the source tracking doesn’t give.
In the case above I would expect they they just didn’t scan it when delivering. We get cases with USPS, usually with appartment buildings that they will leave packages in common spaces and they will be stolen. Although that would usually have a delivery scan.
USPS doesn't tell you much more in this case. It just ends at:
> August 20, 2018, 10:44 pm
> Awaiting Delivery Scan
> The delivery status of your item has not been updated as of August 20, 2018, 10:44 pm. We apologize that it may arrive later than expected.
"Item out for physical delivery" and then... nothing. Usually it should show "delivered" at the end.
Some countries were unusual such as Bahrain, but then the same thing would sometimes happen even for Canada or Norway.
