eCPM jumps high then gets stuck at 0

I know there's already some posts about this. But look. Why did it all the sudden jump to 317?? Then stays at 0 for the rest of the week?

 

You displayed 225 videos and got $20? I have 10 times that and less than half your revenue. Awesome. And 90% of my users are from North America or the UK (it's an english spelling game).

 

Yeah thanks. But now I am getting zero forever xD

 

It'll likely stay at or close to 0 for a long time. With Unity Ads there seems to be a big jump in revenue right at the start. Even if you're getting very few video's completed like us. But then it'll sit there for a long time. From what I've seen with others is that it'll take roughly 2000 - 5000 video's completed to normally get that much revenue. So you'll probably see no change until you get that many. It's almost like they give us an advance, and then we have to "work" it off.
