For making this cleared, if you do not Oberlo for importing products, it won’t be able to bulk update AliExpress links for your products by "1 Click Sync Prodcut" feature. 

You have to update the product manually one by one. To do it, please help me to follow this instruction:

  • Go to AliExpress website, find the original link of a product and copy this link.
  • Go to Product list > Filter “Unknown source” >  Click on “update” button for every single product to update the link manually.
  • Enter product URL (AliExpress product) > Click on "Update" button.
  •  Map variants (if can not auto map).

I hope this helps.
