How to stop scheduled emails in automation after Woo purchase

Hello smart people,

I need some help…

What I’d like to accomplish:
When someone opts into FluentCRM with a specific tag, I want to start an automation that send a few emails first then schedules emails on specific dates. However, if the person buys a WooCommerce product before those dates, those emails shouldn’t be sent.

I’m sending a lot of emails, so I’d prefer not to add too many conditions — and even with that, I don’t see a way to make this work.

I must be setting something up incorrectly.
I’ve added the goal “Order Received in WooCommerce” as an essential point, and after that, I’m cancelling the automation.

It seems like the automation is cancelled, but those scheduled emails are still being sent.

Could someone guide me to documentation that explains this, or simply point out what I’m doing wrong?

Thank you so much for your time!
