I only run ads on the weekends, so I used to tell my campaigns to start on Friday and end on Sunday, but with the new interface I can't do that. I e-mailed AdWords about this and they said that feature has been removed due to U.S. laws. They didn't explain any further... anybody have additional info on this? Now I have to un-pause a campain on the day I want it to start which is very inconvenient to say the least. Is this a drawback for anyone else? Any workarounds?
