Doing some tests, with the site I'm near to deliver for an importatn client, I have enrolled an Audience of 4 users into a Learning Plan (Default), the situation is than I didn't find the way to unsuscribe those users(instances)  from the Learning Plan via the Audience. And even thought the students didn't come unasuscribed  from the Learning Plan once deleted or suspended. 

Can any one suggest what to do? I want to configure every rule & and Lerning Plan from de begening..
