NO BUG: New Mailchimp API key not recognised

Hey, All!

I’m late to this party… but it seems I have the same problem you were all talking about. Was there a definitive solution somewhere?

I plugged in the MailChimp API… saved it twice… selected MailChimp as the action on my form… waited to let the website I’m building sync up with MailChimp…

But they don’t seem to be communicating. When I used hCaptcha with the form, I got an error. When I turned off any kind of captcha, I get a success message but the email address isn’t added to the MailChimp list.
I can’t see the lists or groups or segments or audiences of my MailChimp account on the Bricks backend…

If there’s something I’m missing, I’d love some pointers!
Thanks, everyone!
