I'm trying to track a package from China that is using 4PX. The Android app reports that no status information available yet. However, when I use a tracking site on my computer, I get the following information:
Package status: In transit
Country: China -> United States
2022-01-06 17:19 Yanwen facility - Outbound
2022-01-06 08:30 Last mile=> USPS, number *removed*
2022-01-04 18:58 Processing information input
2022-01-04 12:40 Yanwen Pickup scan
Just thought I would pass on the information that 4PX information is not working in the app.
