I’m experiencing the same issue: continual looping through the approval process with Constant Contact. Hopefully the developer can shed some light on this.
It would be very helpful for me to have additional intuitive classes or id’s attached to the markup generated by your plugin. This would be a huge help for styling.
I found an issue with the tables generated by WC Fields Factory having the class “variations” on a variable product. The “add-to-car-variation.min.js” file in woocommerce empties out all but the first value of selects from WC Fields Factory due to that class being present.
