Okay, let’s find another way then.
I’m looking at it with my programmer and it may be due to the return of the payment gateway.
So, if apart from the plugin (which already measures everything else except the transaction), we put gtm4wp.orderCompletedEEC into the datalayer of the order-received page, and this:
gtm4wp.productClickEEC|gtm4wp.addProductToCartEEC|gtm4wp.removeFromCartEEC|gtm4wp.checkoutOptionEEC|gtm4wp.checkoutStepEEC|gtm4wp.changeDetailViewEEC|gtm4wp.orderCompletedEEC
Into the Tag Manager custom event trigger. Do you think it can work?
Thank you very much for your help
