oh sorry for that issue can you try this code

1. Go to Online Store->Theme->Edit code
2. Asset->/pre_theme.min.css ->paste below code at the bottom of the file.

.sticky_atc_btn .quantity {
    display: none !important;
}

That worked just perfectly! Thank you very much. But the only problem is that it is working on desktop as well, and I only want to remove it on the phone format. Could you add an extra code so that it only removes from the phone format?
