Hi,
Thanks for contacting us here.
The menu icon for mobile users is showing on our demo. If you could share your site url then it will be helpful for us to get the issue behind it.
If you do not want the blue box around the logo then you can remove it by adding the following code at Appearance-> Customize -> Theme Settings
@media screen and (max-width:767px) {
.logo {
background-color: transparent;
}
}
Let us know if you have any other query.
Thanks
