DP ads problem – They’re not working

Question for the support (or for anyone authorized to check our account situation).
Over 15 hours ago, we added for the first time an $50 credit to our DP account as well as 2 ads with high bids.
They're apparently active (after having been approved) but none has been yet shown it seems so we continue to have a balance of $50
May someone help to understand what's happening and if we're doing something wrong, please ?
