I have implemented AdMob in my game and I am seeing zeroes in the game's AdMob page. The game's earnings are reported but this section is displaying all zeroes:
Surely the info you need is at the top where it says seeing all zeroes?
I tried all of those things and they didn't do anything.
Problem is you've come here to ask random user of Construct about Admob because Google's answer or info wasn't good enough. If they can't help I can't really help more than Google. From Construct side the rewarded ads are working in your app.

Unfortunately Admob is incredibly opaque about how it works, there is nothing we can do to help with these kind of cryptic behaviour on their part.
