We've added new starter templates to help you quickly build mobile ad units from a pre-set format. Over 80 ad templates are available, including 29 in-app templates, and all of them are certified to work on DoubleClick Bid Manager.
What about assets, you ask? You can now search and use your DoubleClick Studio assets in the GWD asset library. What about components? We think you'll love the new components: we've added an Image Button (yay!) as well as a calendar component. In addition, you can now create your own components and add them directly into GWD!
