Yes it was, it was done last week. I tested each games and ads were coming up.
Though I have been on Mopub for a long time, so I have a very long list of creatives waiting to be shown in my apps.
I have no admob running right now because I am getting ready to change over to the new admob, since they are forcing out the legacy version. Next month I will update everything again with mopub/admob. Right now, it's just mopub and it seems fine.
