I am playing around with Personalized Catalog Views, as we run our one webstore for US and Canada customers, but some US items aren't sold in Canada and vice versa. I've been able to set this up appropriately (US Customers and CA Customers customer groups, and then US Visibility, CA Visibility, and All Visibility item collections) and it seems to be working EXCEPT for matrix items. When adding a non-matrix item to the US Visibility item collection, our Canada customers don't see it as expected, but if I add a matrix parent item + its child items to the US Visibility item collection, it is still showing for Canada customers. Any ideas on how to fix this are appreciated!
