hello
i have set up the free plug in to give it a try before i purchase the pro version, however, i cannot seem to sync the user groups with the list i set up for testing.
there is one user synced but the rest simply can't be added to the mailchimp list.
there is no error message but nothing is synced.
these are existing users and have not been signed up via the module.... does that make a difference?
What have i forgotten?
