I noticed today that the shipping policies have changed a little. We used to be able to select "Lower 48" for the USA. It now appears that it has been replaced with "United States of America". The changed appears to have happened automatically to the policies that had Lower 48 selected previously. In running a test, it does appear that the USA option also now includes territories.
Just an FYI for people. I have no idea if it means they've also fixed the eBay labels issue for orders from Puerto Rico.
