Mailchimp additions get stuck at “Pending”

Hi there,

I bought the Pro Plugin a few days ago.

Plugin is not working properly though.
Once the form is sent, the logs say that the person has been added to MC, but they never actually get added to the list, NOR do they get a ‘Confirm Subscription’ email from MC when double opt in is selected.

So they get stuck as “Pending” members which also cant be removed easily.
I literally created 12 new email addresses today to test, and no luck.

If you have any suggestions please let me know ASAP!

Thanks,
Chris
