1. No A-scan (completely no tracking updates): This is probably because the carrier is still processing the package. When the package has been despatched over 2 days, you can go to our carrier's website to see the domestic transferring updates, which would sync to 17track later. If it's been over 5 days and you still can't track your package (even on our carrier's website, please contact us) 
2. No updates since "Left XXX": It's common to have a window period after the package has left China to the destination country, usually it would last for 1~2 weeks, depending on the processing efficiency in destination country. The updates would start appearing again after the package is processed locally. When you see no updates after your package leave our city/country, please know that it's not lost or stuck, and is in regular transit.

If unfortunately, the package is lost, we would investigate it with our carrier, after we confirm it's a fact, we'll arrange another shipping or fully reimburse you.
