Hello,
1.
another question while we look at this, on the mobile we have a On Sale part now on computers it shows the Sale bubble but on mobiles it does not, can this work to show the sale bubbles.
– please provide screenshots for better understanding.
2. Try to add this code in Theme Options > Custom css > Custom css for mobile:
.products-grid .product {
width: 50% !important;
}
Regards
