Advertisements not showing up in the release build

So currently we are developing a game. We are running the latest Unity beta with the UnityAds imported from the services window. When i make an export and run the app through xCode everything works fine. The advertisements do get initialized properly. But whenever i archive the project and distribute it the Advertisement.isReady() always (and i mean always) returns false (i waited for around 2 days). This does not happen whenever i try to build it directly from xCode.

It seems like there...
