Advertising API - Invalid Scopes when trying to access anything other than profile


Following this guide:

I run into invalid scope errors while trying to access any scope other than profile, for Login With Amazon. Using the profile scope, I can get my authorization code and subsequently my access and refresh tokens but can’t access anything other than my own profile data.

Looking through other forums with similar problems, they need to apply for API access here:

Which I did, receiving this email:

I connected internally about the topic and got certain permissions but still receive the same scope errors. What do I need to do in order to whitelist my application and eventually pull performance reports?
