Hi
I recently published a game to Google Play. When I download it on my phone and press to watch an Ad everything works fine. Some people have told me that when they do it nothing happens. No ad is delivered to them. Seems like some people don't get the ads at all, and some do. Why does this happen? Are there no ads available for them at that time?
Please help me with this. I was thinking that something is wrong somewhere, idk.
Thank you!
