Advice on the SDK forums was kafkaesque, telling me that I couldn't contact support directly because I wasn't part of a "certain group of developers" -- that group being those who earn $25/month.

I can't earn anything if I can't enter Payment info.

I tried creating a new Google account and ran into the same issue.

Console:

I have an app getting 100 downloads a day in China on iOS. I need to ad ad support to this app + get banner ads in the Android version coming as soon as I can setup payments and submit to the Play Store.
