I use Customize to set Woocommerce Shop into 3 columns in PC mode and 1 column in mobile mode. It’s ok when I view on Customize mobile mode. But when I use several smartphones to test, Woocommerce Shop still have 3 columns in mobile mode.
The problem is similar with Woocommerce single product: 2 columns for the product image and the product title, instead of just only 1 column.
I have cleared WP rocket cache.
Please support me. Thank you.
