Template tag %event_venue_map% broken

The template tag %event_venue_map% is broken

Google have changed the way they display maps, which could be part of the cause – the following works for me

// comments below include possible default values.

   // $address="%event_venue%, %event_venue_address%, %event_venue_city%, %event_venue_postcode%"

   $map = '<iframe ';
   $map .= 'width="' . $width . '" ';  // $width=800
   $map .= 'height="' . $height . '" ';  // $heigh=450
   $map .= 'frameborder="' . $border_width . '" ';  // $border_width=0
   $map .= 'style="' . $style . '" ';  // $style='border:0',
   $map .= 'zoom=' . $zoom ;  // $zoom=21
   $map .= 'src="https://www.google.com/maps/embed/v1/place?'
   $map .= 'key=' . $google_key;  // you probably want user/webmaster to generate her/his own key with google
   $map .= '&q=' . $address;  // see suggested address above
   $map .= ''">';
   $map .= '</iframe>';
