I use GWD for some time already, but I have a problem when I make banners in doubleclick environment.
After the first save, when I check the preview (Chrome), I don't see the banner.
It seem that is attributed opacity = 0 to the <body>.
But this problem occurs every time that I work in doubleclick environment.
How can I fix the problem?
I've seen similar questions but are dated almost a year ago .... any new solution?
(I also checked for html (https://h5validator.appspot.com/dcm) banners are correct ... but I still can not present a preview, and I don't know if once uploaded on Studio these banners can work)
