Is it possible to limit to one per category while allowing unlimited quantities?

Hi Jonas,

Unfortunately, no – currently the plugin will require you to set max quantity for the product, so the closest solution would be to set max quantity to 1 for the category, i.e. customers will be able to buy only one product per category, but the quantity has also to be 1. Let me check if I can implement your task in the plugin. I will get back to you as soon as I can.
