WP Bannerize deactivates on mobile view

me too. In default browser of Android 4.2.2.

A temporal fix is add a change in the line 64 of wp-bannerize/Classes/wpBannerizeWidget.php

function widget( $args, $instance ) {
    global $wpBannerizeFrontend;
    $new_args = array_merge( $args, $instance );
    if (isset($wpBannerizeFrontend)) // add this line
        echo $wpBannerizeFrontend->bannerize( $new_args );
}
