Can't activate unity ads: "Forbidden"

Hello, when i try to activate unity ads, i got a “Forbidden” message showing up, i’m using Unity 2017.1.0f3, on my client’s side (which is the owner of the project), it works, he can activate it without error, and on my side, i can’t, which is bad since im the only one knowing how to code.

What can i do?

edit:

Seems that for now we need to be main owner in order to activate ads on the project, or access the project ads settings on dashboard.

I am also seeing this

Did you ever get it to work?
