Hi,
We don't have Recommendations but Target Standard. I'd like to use the Category Affinity algoritme, and are sending in product category as you can see in the request example below.
However, setting up an XT activity using a audience where I uses the Category Affinity doesn't put me into the activity.

I'm wondering if the Category Affinity only works with a product-collector mbox or if I can use the global?
Hope someone can clarify this to me
