Mailchimp Add On - Stuck on getting it working

    Hi there,


    I've updated an older site to Perch V3 and in the process added the Mailchimp add on. However I cannot get the form to work and not sure what steps I may have missed?


    Here is is what I've tried so far.

    1. Set up new Free mail chimp account with one audience
    2. Updated my site to latest version of Perch, Mailchimp add on and PHP 7 on the server
    3. Installed mail chip and added the API key to my dashboard
    4. Set up the example subscription form here: Mailchimp Test and included the Mailchimp embedded form
    5. Checked the Webhooks are right on the site and in Mailchimp dashboard.
    6. Checked that the API is logging the API requests at the right times, which it is


    The Perch example form doesn't work locally or live but the Mailchimp example does when I try to add a new user.


    Have I missed any steps?


    Thanks in advance
