There are 2 reasons make Shopify orders do not show up on the Ali Orders's Order List: payment status, OR the product was removed from Ali Orders app.
1. Payment Status
Ali Orders only shows orders which are marked as “PAID” in Shopify. Mark the order as paid, and then check if it appeared in Order List.
2. Product was removed from Ali Orders's Product List
Check the products that have orders still exist in your Product List.
If it's still in the Product List, there is highly a problem of syncing orders. Please feel free to contact our Support team via our live chat channel by clicking on the bottom right icon inside app, or our email at email@example.com for further support.
