Despite the API key integration of Mailchimp in Jotform, contacts do not import

I think I have done all what I should and did not receive any error message. But the new contacts still do not appear in the indicated list in Mailchimp ... What could  be the reason ? 

We would be more than happy to take a look at this problem you are having with Mailchimp.

Can you please tell us the name of the form or provide us with a link to it so that we can investigate?
