Answer 1

I had the similar problem. The internet connection was OK and there was no ad blocker installed.

The problem might be related with your test device. Check if you have another application that contains Admob with your test device. You can also check with another device and another app that contains Admob.

In my case I realized that my test device has the internet connection but doesn't show up any Admob ads in different applications. So I tried to restart my test device and It worked.
