I'm using the Perch Mailchimp app and can successfully add subscribers to a list, but I'd also like to add tags to subscribers which I can't get to work.
I've added the mailer="interests" tags to my form and retrieved the tag id's from the Mailchimp Playground however checking the API logs I get the following error:
I'm not entirely sure how to check the 'errors' array.. but I've narrowed the issue down to the tags (as it works without).
Does mailer="interests" work with Mailchimp tags? I understand tags is how they now handle segmentation of subscribers within a list.
