Version 3.3.8 issue : Header Widget Not Displaying

Hi there to the team,

After updating to version 3.3.8, the header advertising widget has stopped displaying (in mobile devices – iPhones & iPad).

In one of the old threads BD Brown had sorted out this issue for me (for a previous version of Hueman and it was working fine until the last update) with the following CSS:

/* always display header widgets */
#header-widgets {
    display: block !important;
}
#header-widgets {
    max-width: 728px;
    width: 100%;
}@media only screen and (max-width: 728px) {
  #header-widgets {
    display: block !important;
  }
}
/* changes for iPad viewport */
@media only screen and (max-width: 1200px){
    /* remove top padding */
    #header .pad {
        padding-top: 0;
    }
    /* adjust and center title */
    .site-title {
        padding: 30px 0;
        width: 100%;
        float: none;
        line-height: 50px;
    }
    .site-title a {
        text-align: center;
    }
    /* hide description */
    .site-description {
	display: none;
    }
    /* center ads widget container */
    #header-widgets {
        max-width: 728px;
        width: 100%;
	float: none;
	margin: 0 auto;
    }
}

The code above made the header widget ad appear & properly centered on all the devices – Desktop, mobile & tablets. But after updating to 3.3.8 the header ad widget is not appearing at all. (in mobile & tablets) Here & Here.

The header ad widget is a very prominent advertising position in all devices particularly in mobile & tablet.

Any help in this regard is very much appreciated.
