Admob ads not loading - Failed to load ad: 0

Question

I am trying to load Admob Native ads. Previously (before app was updated) ads used to show but now they are not showing. I have posted the code, xml and the Logcat below.

Answer 1

When it works with the sample ad unit Ids your account probably just is not approved yet. Have you created it just now?

Test ads worked right away for me. I had to wait several hours for the "Great news – your account is now approved" mail until my ads worked too. Do not use your own ads for development anyway - you can get your AdMob account blocked for that!

So as soon as the test ads work and you have confirmed that the correct IDs are used for release build you most probably have done everything right and just have to wait

There is also an test App ID "ca-app-pub-3940256099942544~3347511713" but I had no problem to use my own App ID right after creating it.
