So I have accidentally uploaded to Testl lab (Robo test) an apk (.aab) that was uploaded a few months ago to PlayStore and has admob working in it with real ads. I have seen in the video that the robo test has done like 20 clicks in an ad and I am afraid my admob account could be banned.
Not to worry. Admob ignores clicks that come from test lab. See https://firebase.google.com/docs/test-lab/android/get-started#mobile-advertising
