AdMob ads not showing after app update

I had an app at Play Store that requested and received real ads successfully, no problem. But recently I uploaded the updated version, now the app is updated but ads are not showing. To test it, I emailed the same apk to my distant friend. He installed it (out of Play Store) and ads work. Any idea why it works out of Play Store and not from the Play Store? And is there any solution?

List of ideas: Firewall, AdBlocker on device, Internet error, Admob was down, government regulators (Chinese mega firewall or Russian Roskomnadzor or ads is 18+ and account on device belongs to minor) …

Check device logcat for any errors.
