I am developing a fulfillment service app for shopify. Recently the tracking became unavailable up until the order is delivered.
I have successfully updated the tracking info before and it appeared in Order view. See the screenshots below. Now I can only see tracking info when the order is already delivered. I can confirm that the shipment status is correctly updated, but not shown in Order page.
They say, I might need an actual paid plan for the tracking to work, but why did it work before then?
