How do i extend or add new categories in my shopping campaigns?
You should not click on create button to create new categories for a shopping campaign you have created.
use the extend shopping button in the campaign group page to do so.
In the dialog box which will open, you can select new categories to advertise and this will create new campaigns automatically
