Howdy Carolyn,
oh, well that is good to know but it might be something you add a flag or something to AdCenter which tells you that you also just updated ads x,y, and z. Otherwise, how to you know what you are updating since only one ad for one campaign is displayed at a time? I am not so sure this is a good design. I could see how it could work as a benefit if you wanted to bulge change ads, but then maybe that should be a separate bulk ad change tool rather than some code working in the background that we don't even know that it did something.
Thanks,
dave.
