Can you please tell us the URL of your form that uses MailChimp integration. I tried checking the forms on your account, but I could not find the form the uses MailChimp integration.
I also test the integration on my form and it was working just fine at this time. I was able to integrate my form to MailChimp.
We will look into it more once we identify your form that have the issue.
