Yesterday I shipped 11 items.
When I returned from the post office, I entered the tracking numbers into Paypal as normal.
I expected those numbers to automatically register on Ebay too, as they usually do.
Today I discovered that Ebay populated 9 of those 11 tracking numbers, and failed to populate the other 2.
These two were, one Tracked Packet item to the US. And one Tracked Packet International item to Australia.
Luckily I noticed this today, before Ebay gave me defects for falsely claiming I did not ship on time.
