Background image for newsletter is cropped on mobile view

Site URL: https://www.archiesofcheltenham.co.uk

At the bottom of our home page is a newsletter block. The background is an image, however this image is cropped on mobile view. What code can I enter to show it fully on mobile view and desktop?

Thank you

Hi @Meganowilliams Add this code to Design > Custom CSS > Save & reload your site

/* resize newsletter background */
@media screen and (max-width:767px) {
[data-section-id="6007255bd9cfee4ce9810a30"] {
    min-height: unset !important;
    height: 70vh;
}
}

Thank you but that hasn't changed when viewing on a mobile
