Hey, thanks for reaching out!
Although we would love to help you sort those mobile related posts out with some CSS magic, allow us to provide you the "non-mobile" solution as well. You can find the CSS code below, which you enter in your 'Customize CSS' window in your plugin settings page:
@media screen and (max-width: 480px){
.wp_rp_content {
display: none !important;
}
.related_post_title {
display: none !important;
}
ul.related_post {display: none !important;
}
ul.related_post li {display: none !important;
}
ul.related_post li a {display: none !important;
}
ul.related_post li img {display: none !important;
}
}
Let me know how it goes or if you have any questions what-so-ever, since I'll gladly help you out! Take care & have a nice day!
Best,
Silvo
