Has anyone come across this before?
I have attached a medrec that shows the issue. It works normally and is above all image items in the timeline in Google Web Designer but when rendered out and then uploaded to doubleclick the centre area is not clickable (which you can see in preview mode in doubleclick).
1. Go to the Code View in GWD
2. Look for this CSS class in the code: .gwd-page-content
3. Set the "transform-style" as "flat"
4. Republish your creative.
Please see the attached updated index file and let me know if this works for you.
Hope this helps!
