If there are 2 product views in the customizer and the customer only customizes the second one (which happens for some of my products) the thumbnail preview in the cart shows a blank design, which is the first product view. How can we get it to show only the product view they customized?
Hope that makes sense.
With the plugin as it is that is currently not possible. You could make a feature request for a feature that would allow this or do some custom development.
