Hi,
I use Odoo v11. I searched how tro refund a product in Odoo POS and found everywhere that it's simple as clicking on the +/- button. But when I only have a 2.99$ product to refund, and nothing else oon the invoice, when I click on the +/-, it put the product price 0.00$ and not -2.99$.
Do i miss something?
Thanks!
