I cannot get to the bottom of why my flows are failing, here is a screenshot. It did passed once and I got the email, but most of the time it’s failing upon my tests.
This is happening with Browse Abandonment but also with Abandoned Cart.
Also I’m trying to understand how an ‘event’ is triggered, does it use the browser cache to recognise who the user is. Do they only need to be a newsletter subscriber to be recognised? What is the browser cache is cleared, does it no longer recognise the user?
