Does anyone have any knowledge as to why Yahoo stops showing all but one of my ads? I will set up a campaign with multiple ads, all will run for a couple of days, maybe less, and then inexplicably, all are paused except one, which I would assume is the best performing ad. Is there a way to stop this? This happens on every campaign I create, and obviously I would like to have more than one ad running per campaign, but I can't because Yahoo shuts them down without me knowing. Any info or advice regarding this pain in the ass would be greatly appreciated. Thanks.
