background color not showing on Galaxy S7

Hi. This is a staging site.. so hence the weird URL! But when I preview my page created with Elementor in Mobile view things look correct with the correct background color. But when I view the page on my mobile phone(Galaxy S7) I get a white background. I fooled around with some Media Queries using the Custom CSS plugin( I also use Elementor Pro with CSS editing) but same results.

The page I need help with: [log in to see the link]
