I get the black ad sometimes. I'll wait about 15 seconds before exiting the add (Android back button). Then I get it again and sometimes it works... sometimes not. If it doesn't work the 2nd time I exit the game, rest ad ID and then I get a new ad. I think the reset is key. You can do it on both Android and iOS (so I'm told).
