Frustratingly, I was about to take a screengrab when I simply closed the ad! - it’s a standard install, initiated on the main.lua with the interstitialAppID - and I simply used the ads.load( “interstitial”), followed by ads.show( “interstitial”) on the next scene.
The broken interstitial ad loaded full screen - with the cross top left, and the blue i top right… I’d seen the ad before, and the rest was simply top half black (where a video or static graphic would go) and bottom half white where the ad text went. It was just the ad without content.
I’ve since changed over to test mode again, but I was since testing as a paid user without seeing the ads after I clocked them working. (they did their job, I was annoyed by them!)…
