Hey, so I've set up everything in mopub according to the tutorial, using CocoonJS, Mopub and Admob.
Good thing is, I'm seeing ads, no "This is a Mopub test ad", but ad pictures.
However I do not know where these ads come from. My Admob fillrate is 0 as seen here:
My app can be found searching for "Derqs" in the playstore.
Could I have missed something or is this a common issue?
