We are switching from Envy 1.0 to Envy 2.0 but noticed that choosing thumbnails is not changing the variant option. Variants display correctly and the picture changes correctly when you select variant options. However, it is not working the other way, selecting a picture (thumbnail) is not changing the variant option. We noticed that it is not specific to our theme. We tried several 2.0 themes but they all do the same thing. It can be problematic since customers might purchase another color if they don't notice the variant had not changed when they clicked on a thumbnail. Anyone got a code or workaround solution to this?
