Editing mobile/desktop theme

[Arturk9913]

Hello, I have a problem with mobile theme.

1.I want to delete all banners and slider on homepage but only for mobile device.I tried with AP PageBuilder profile builder - Duplicate profile homepage, but then page loading around 8 second, if not its ok with loading....how I can edit the design without creating new profile?

2.Second problem, at the product I must add the picture 1000x1000x to be full product size, but as I know it's must be around 270x270. How I can change it to this size with full width and height?(this same at desktop and mobile)Attached 2 photos.

3.How to delete no taxes at the product page? Attached photo

4. How to make on mobile 2 products in the row at homepage?I got carousel on the homepage.I need that because one product on all screen,its very bad looking, when you got 70 products+
