So I released a game a few days ago and it seems to be getting unusually low impressions considering how many installs it's getting. For example, on one day it had 2,044 new users but only 46 ad impressions. I'm pretty sure my ad implementation is working properly... And the ads are shown after the tutorial and after each round in the game -- there are voluntary rewarded ads as well. All of this seems to be working fine -- but why the low impressions? Is there a delay in the stat reporting? Thanks in advance for any assistance you can provide!
