The subscribe action functions correctly, but fails to setup the group according to the value entered in the admin:
The group label matches the value setup in Mailchimp for that list:
But in the tests, the group does not get filled in on the record added by the plug-in via the check-out process:
I've enabled wp-debug but did not notice any errors being reported.
Do I need to enter the group ID instead of the label, or is this just another bug caused by the WooCommerce 2.1 update?
P.S. I've even tried to enter that value in the 'groups' section and that did not help either.
