Hi Gulfaran,
Thanks for getting back to us and for doing extra effort to troubleshoot this.
You may refer in
this guide on how to setup your test devices properly. Also, I noticed that in your screenshots, one of the Banner Ad has the Test Ad label while the other has no Test Ad label. I assume that the one with the Test Ad label is the native Android app while the other is the Unity game.
Once you capture another set of device logs, please check if you see the "This request is sent from a test device." log message. This log message is only thrown when an Ad was loaded from a Test Device, which will be treated as a Test Ad.
That said, I already raised this to the rest of the team as we received a similar report and I'll get back to you for any official feedback.
