Hi,We're having a flicker problem too. We tried different methods to hide the body and we tried the hack suggested here and we still see the old content before seeing the new content. We're currently using mbox version 63 and we can't change to at.js right now. Would you have any suggestion to fix this problem?Code:.FH .promo-overview {display: none;}jQuery('html').addClass('FH');var intervalCode = setInterval(function() { if (jQuery('.promo-simple-image').length >= 0) { clearInterval(intervalCode); jQuery('.promo-simple-image img').attr('src','cq5dam.web.690.388.jpeg'); jQuery('.promo-overview').show(); }}, 100);
