Not adding affiliate to MailChimp mailing list

Hi!

I have the plugin installed, an active API key added, I’ve selected the list I want the affiliates to be added to, and I have selected the “don’t show checkbox, just add them” option, but they’re not being added.

I’m certain you need more info, so please let me know what to send you. Just looking to make this happen without duplication of effort on my part.

Many thanks!
