Hello recently I noticed that my packages that was mailed to me via Korea Post and registered, does not update correctly? The tracking number usually starts with an RA and ends with a KR. It would track the package until it reaches International Airport then it stops there. However when I check the eBay tracking, it is able to track it when USPS gets the package and delivered to me. I tried changing it to USPS instead of Korea Post but it would say the tracking is unavailable.this seems to be a recent issue.
