I am having difficulty filtering using custom taxonomies in the Advanced Tab. By selecting the taxonomy and entering a post in that taxonomy does not auto select the account. Adding a custom Taxonomy tag in the form Cust_taxonomy|tag does not help either as it does not select the right account or in fact any account when you add the approropriate tag.
Is this a bug, not intended or am I doing something wrong here.
You need to be extra careful, Cust_taxonomy|tag format is correct but you need to make sure you are suing the right words there. You need to use slugs exactly as you have them in WP
