I have Banner and Interstitial Adverts in my game.
The bottom Banner only shows when the full screen menu is opened.
Right now I create it not shown on game start, show it when the menu opens and hide it when the menu closes.
I test it by exporting it to iOS and it works once, but won't become visible the second time when I open the menu. I'm never leaving layout btw.
Similar with the Interstitial Advert. I use it like a "tip button" so you can watch an ad to support me.
Upon tapping the button the advert gets created (shown: true). This works when testing once and I see the test advert. But after closing the ad, nothing happens when pushing the button again.
Are those limitations of the test mode? I have no frequency capping in my Admob settings.
