Hi @Funkaholik
Old interactions are not gone - and will apparently stay around on sites that have them even when they are (eventually) phased out. See @thesergie response here: Legacy Interactions - NO! - #15 by vincent
What I think you need to do is select the book agent button, then go to the interactions panel, then select legacy interactions, and you should get the option to apply them from there…
Does that help?
