I am using the Mailchimp plugin and have had great success for the past few months but starting yesterday I noticed that MC was not updating names/info to my list. I would get the notification email from GF but nothing else (as I am signing myself up for testing purposes). On the MC API screen I can see that there are red octagons showing failure in the results column. Ideas? I have uninstalled the MC add-on and re-installed and setup feeds again to no avail. Do I need to scrub the database of all things MC and start over?
