When I download the template "IAB Mobile Full Page Flex template" from this link http://www.adform.com/site/files/manuals/ZIP/FullPageFlex.zip and run it on my local pc, the close button does not work whereby clicking it fade outs the ad banner but right after that the ad banner returns to full opacity. Same goes when I placed it in Google DFP and used it for my Website.
