Hi Alessio,
Thanks for reaching out! I hope you’re having a great day.
I was able to replicate the same scenario on my end, and I believe you are correct. At the moment, the only available option is to hide the “Add to Cart” button when stock is below the minimum quantity. By default, the plugin still allows adding products to the cart even when the stock is below the set minimum quantity.
If this solution works for you, you can enable it by navigating to the Minimum Quantity tab—this setting is located at the bottom of the options.
That said, I have escalated this issue to our development team for further review, and we will update you as soon as possible.
Please let me know if you need any further assistance. I’m happy to help!
