I’m able to add items to our cart via the add to cart remote widget, and get successful update of our remote cart widget. I can also navigate to our shop domain and see the item I just added in my cart there, but when I click on View Cart from either the remote site or the shop domain site, the cart loads empty. If I click Checkout, an empty cart loads. Refreshing the other places (remote widget, shop domain) additionally shows an empty cart now.
Any idea what is going on here?
