Same here, I’ve done all the steps you could ever imagine and the ads from admob still wont show up. A lot of other people have asked this question too and no-one seems to care / know how to do it so that it actually works. It’s quite sad, basically forces me to develop for PC rather than android. Since selling an android app for money isn’t really profitable, and I would rather that the players didn’t have to pay to play my game. (Nor do I want to spam the game with adds, just one subtle advertisement in between levels… that way I get money and people get to play for free, win win)
