so, I'm back with the same problem: on some of my product, the default variant is added to the cart, whatever I try to do.
And this happen in a totally random fashion, on products that were fine the day before and not working today, while I haven't touch the code in between.
In order to get some help from you, I've left one such product live on my shop for the moment:
and the same product page, just duplicated this morning, nothing else changed, is working fine here :
Any idea what is causing this?
When I duplicate the product sheet, doing NOTHING else, it works fine again...
Many thanks in advance for your help on this!
