To link an automation to a new funnel in GHL, you must ensure that the automation begins with the correct trigger. For instance, if you are capturing leads, you can use the "Lead Form" trigger.
If the automation involves purchases, you should use the "Order Submitted Product" trigger. Updating the trigger will ensure the automation aligns appropriately with your new funnel.
