SugarChimp

Hello, we realized that the mailchimp activities are not being updated and synced with the crm, although they do appear inside the dashlet Mailchimp activity. This would be useful because we would like to find a way of filtering leads who have responded to a specific campaign ( clicked) for example. Do you suggest any way of filtering the leads by Mailchimp activities inside sugar crm? We have tried reports but they won't work since the mailchimp activities are old and do not reflect the reality. Also, we tried with the mailchimp stars rating, but they don't update based on the results of automated campaigns. Thank you, really appreciate if you can provide any insight about it.
