Before launching a new game, we tested Android phone admob ads. (Buildbox Classic 2.21.1 /#2722) Both banner and interstitial ads are executed without any abnormality, but interstitial ads are executed only once for the first time and do not appear. I set it to come out after 4 game overs, and even if I run the game again, it only comes out once and it doesn't come out after that. I have attached a photo. Thank you for always.
