Hello,

Find and replace this code in the Theme Settings > Custom CSS > Global:

body .mobile-nav ul li a:hover{
    color: red;
}

body .mobile-nav ul li a:hover,
body .mobile-nav ul li a:focus{
    color: red;
}
body .color-scheme-dark .sub-menu li a:hover{
    color: red;
}

Copy the code from forum not from email

Best Regards
