A new check box has appeared in the recently updated listing creation dashboard now non of my listings are showing to ship internationally unless I manually go in and change them each…which would take me literally hours…is anyone else having this issue??
No new apps have been installed and it was a shopify update that has alerted all my listings…
I have not changed any settings in my shipping settings.
YES! I’m going spare. 
It’s a great feature, but OMG the time it would take to do it all manually. I have complained to shopify about this. There was zero warning, and I only noticed it today, so how many sales might I have lost?!
It’s a great idea for a feature, but it needed communicating with PLENTY of warning and an option in the bulk editor to select all (which currently there isn’t). I do have products that I can’t ship internationally, so I’m pleased to see the feature, but it needed to be done much more cleverly and with plenty of notice. When I spoke to support, they were completely unaware of the change.
The only workaround I can suggest is going into the bulk editor, and setting a country of origin or HS code for all the products/variants you want to allow international shipping for. That seems to make the system tick the box for international shipping. It’s a pain to do, but I guess you don’t need to be accurate with the HS code/CO in order to trigger the system to allow international shipping.
I wonder if it’s precurser a rollout of Shopify international shipping labels or something? It would explain why they insist on having HS Code/COO for each and every product. The oversight is bundled items which have more than one code per ‘product’.
