I was curious to see if anyone else was having issues with the 17track site. We are currently using BulkFulfill to import our tracking & the site it goes to(17Track), doesn't work half the time or gives false information.
Does anyone know of a bulk tracking fulfillment app on Shopify that will go straight to the carriers site?
May I know which Courier you required the most..? There are several site that provides same result as official websites shows at real time.
Many people trouble the same issues arise like you faced.
