If Connectr ships via FBA successfully but does not update Shopify order status or tracking, check the following:
1. Misconfigured Shopify order processing settings
Go to Shopify Admin > Settings > General > Order processing.
Set After an order has been paid to Do not automatically fulfil any of the order's line items.
Important: If this is set to automatically fulfill line items, Connectr cannot update Shopify order status.
2. Shopify Fulfilment by Amazon integration is active
If you use Connectr to ship via FBA, deactivate Shopify's built-in Fulfilment by Amazon integration. Leaving it active prevents Connectr from updating order status correctly and can cause duplicate shipments for the same order.
Steps to deactivate are in Shopify's Fulfillment by Amazon guide.
