Flow “Fulfillment order ready to fulfill” not running for one fulfillment order in multi-FO orders

Hi everyone,

I’m running into a very frustrating Shopify Flow issue and I’m hoping someone in the community has seen this before.

Context

We use a Flow called:

“Warehouse X Fulfillment Request: Auto Submit + Tag Update”

The purpose is simple:

  • Flow trigger: When a fulfillment order is ready to fulfill

  • AND the shipping country is Canada

  • AND the fulfillment order is assigned to our warehouse X location
    → Wait 3 hours
    → Submit a fulfillment request automatically

The problem

This works perfectly when an order has only 2 fulfillment orders, for example:

  • Warehouse X location FO

  • Warehouse Z location FO (Shipping Insurance)

Flow runs correctly and submits the fulfillment request for Warehouse X.

Issue appears when an order has Warehouse X and Z.

Attached example order has three fulfillment orders:

  1. Warehouse Z location FO (Shipping Insurance)

  2. Warehouse Y location FO

  3. Warehouse X location FO

What happens:

  • Flow runs for the first two fulfillment orders (Warehouse Y + Z) and fails the condition (expected)

  • Flow does NOT run at all for the Warehouse X location fulfillment order

There is no Flow run created for the Warehouse X fulfillment order, meaning the trigger itself never fires for that FO.

Important detail

The Warehouse X fulfillment order is assigned correctly from the beginning (confirmed in order timeline).

So this is not a location reassignment issue.

It seems like the presence of a “Warehouse Y” fulfillment order prevents Shopify Flow from triggering “Fulfillment order ready to fulfill” for the warehouse X FO.

Any insight would be highly appreciated, Shopify support hasn’t been able to explain why the Warehouse X fulfillment order never generates a Flow run when there’s another FO for Warehouse Y and we have back and forth more than 2 weeks now.

Thanks so much!

Can you share any links to support your answer – I have never experienced this limitation myself and can’t find anything similar?

@good_4our_you Thank you so much for the recommendation! I tested the first pattern you recommended this morning, and it’s resolved! :tada:
