Hi. I have a suggestion regarding the add to cart button. Maybe you can implement this as a second option, if not the default one.
Scenario: Remove the quantity selector on the product page, leave only the add to cart button, so the user can adjust the quantity only on the cart page. And on the cart page, replace adjust stock selector “-/+” with a dropdown list with maximum quantity allowed based on the quantity left for that certain item (see screenshot: http://prnt.sc/w4k23g)
This way, the problem I described on this topic will be solved: https://xtemos.com/forums/topic/sticky-add-to-cart-mobile-2/
Because the selector will dissapear from the sticky add to cart button on mobile.
Thank you
