Unable to add Gmail Ads
I am trying to add Gmail ads to my clients GDN campaign. I have all the emails in there and I have all of the settings correct on this page: https://support.google.com/adwords/answer/6105478?hl=en
but when I click on +Ad, there is no option to add a Gmail ad. Any suggestions as why this is happening? Is there another setting I am missing? I am located in Canada, so maybe that is why?
