I haven't seen that problem since the very first year promoted listings launched @jcdeals4u .
Have you considered listing without promoted listings, then at the end of the day manage your campaign to add all the new listings - at least until the problem is fixed?

I also suggest clicking the ? icon on the bottom right of the page if on website (shake your phone if on the app) to trigger the screen to file a tech report.
