I don't use AliExpress. I have a supplier. I send them an export of orders from Shopify and they send me same file back with an extra coulmn 'Tracking numbers'. Now Shopify doesn't let you add tracking numbers to orders in bulk. Someone said SHipstation can, so I installed it. But so far no luck. Can anyone guide me how this can be done? I need to add trackings in bulk, so that I can see them 'IN SHOPIFY' when I open my orders there.
