Hello,
Thank you for your response, apologies for the late follow-up from us on this subject.
The issue is that when you are on a product page there is always a default form value selected. We can naturally turn this off, but we would prefer to have a variant pre-selected. What happens is that when the preselected variant is out of stock nothing is selectable anymore on the product page. Instead, it would be ideal that the next variant in line would be the preselected variant in case the previous one is out of stock.
I know this sounds a bit complicated, please let me know if you need further clarification.
Looking forward to your response.
