Problems with compatability

Hi,

Have some problems with compatability of the homepage on mobile devices, using built-in WP editor.

1. For one of the blocks I used built-in Woocommerce widget and chose option “display picked-up” products, 3 columns. On laptops it looks nice, but on mobile devices still remain 3 columns (in other Woo blocks of the site, for example Shop, on mobile is shown 1 column automatically).
Tried Elementor and Gutenberg, the same thing.
Also didn’t find anything in theme settings.
Please help, maybe somebody had the same problem and how it could be solved?
If CSS, what parametres change in additional styles?

2. The same problem of compatability with using Images/ Cover functions via editor. I set picture 1200×400 px which is wonderful on laptops, but on mobile it seems either very small (with same proportions 3:1), either if I use option Cover it is cutted by center. Optimally is to use different images on computer/ mobile versions, but I didn’t find such options in theme/ Elementor/ many other tested plugins. How could it be realized in OceanWP?

Great thanks in advance.
