On the most recent update the click and drop export function now exports to a "full name" field, rather than separate "first name" and "last name".
While "full name" can be mapped within click and drop, "first name" and "last name" are still required fields and therefore it will not allow you to proceed with the import.
I have reverted back to an old version of packing partner as a workaround, but please can this be fixed?
After pressing the Carrier (upload) button On import, change all the columns to match, and then select "First and last names are combined" from the Name Format dropdown menu.
Then it will say all fields have been mapped.
