Pop Up Form Isn't Connecting to Mailchimp
I recently set up a Hubspot popup form on a client's free hubspot account. When I go to edit the pop up and "select lists" for mailchimp, a notice comes up that says "error saving changes:" but nothing else and won't let me save it to push these new leads to mailchimp. I don't know where to go as the error message doesn't give me anymore information.
Thank you in advance!
