Hello I'm beginner at advertising, but I don't understand why there's 0 reach. I payed 1€ (about 2$) to test out advertising for first time. I thought that it would reach at least one or two people. But my reach is 0?? Why there's no reach, I don't understand. I targeted everything I clicked on categories, age etc.. It said that reach will be about 500-2500. *The ad is active, the only thing move is time, time-left is: 9 hours now.
