Bad adaptation 300x640 in Mobile Sydney

Hello, recently switched to the topic of Sydney. Faced the problem of adaptability on mobile devices (especially at 300x640).

I use the Elementor plugin.

Hello, I’m not sure what exactly is your issue.

Can you please provide some explanatory screenshots?

Kind Regards, Roman.
