I'm trying to setup new cross promotion rules for the first time but am having issues setting up default rules. No matter what I select as a keyword I get the error "The keyword you have entered is not valid. Please enter a different keyword." The words I have tried are words in my listing title. I've tried single words and multiple words separated by commas (not sure if that is the delimiter required as there isn't information on how to set this up correctly). I've tried the entire title too. Has anyone had any luck with setting up cross promotions? Many thanks.
