My Ad Demos Work Perfectly but I Still Get "Unity Ads Integration Required"

Hi,

I've got the demo ads working fine on pc and I've exported the game to my iPhone too. Everything seems to be working except that when I go to the unity dashboard, the panel which usually shows the eCPM looks like this: https://imgur.com/gallery/nyhLClf.

I don't know if this is due to lack of impressions, but could someone please clarify what this means?

Much thanks.
