Mail Chimp Integration - Does not work if you have auto responders turned on for your forms?

I noticed when re-testing some sign up forms today that they no longer synched with Mail Chimp if you set the auto responders to active. Is this by design or possibly a bug?

My client requires an auto-responder and the Mail Chimp to work together.

I’m having this issue as well. Please advise. In addition will new subscribers receive the final welcome email if setup in Mailchimp?

I tested a site today that I have set up with both autoresponders and Mailchimp subscription and it’s still working (v4.0.0 AU Datacenter).
Are you receiving the Mailchimp opt-in email?
The contact won’t be subscribed until that’s actioned (if it’s enabled I guess).
