Yea so I still have $0 revenue and I'm not sure why. I've contacted mopub but I don't know what they're trying to say in their response and they closed the ticket (I will have to wait another 2 days for a response).
Their message: Looking at your UI, I'm not able to see any impressions for AdMob or Marketplace: https://app.mopub.com/networks/v2/
If you made any changes after the first ticket and turned off the mediation through MoPub, that might be the reason for why we are not seeing any data.
If anyone could help me, that would be cool. I'm just posting here because it is easier to get an instant response with people who may have had the same experience.
