Hello,
1.1 Add the next code in Theme Options > Theme custom CSS > Mobile:
.single-product .swiper-control-bottom {
display: none;
}
1.2 There is no such possibility, unfortunately.
2. Try to activate “Hover buttons on mobile” via Theme Options > WooCommerce > Shop > Products style.
3. There is no such possibility, unfortunately.
4. Custom CSS for mobile:
.content-product {
margin-bottom: 0px;
}
Regards
