Anyone been able to publish their writing through Google Play Books now that it's recently been made available in New Zealand?

I signed up to the Books Partner Center, uploaded my files and filled in all the forms I could see, seemed simple enough, though I couldn't find the pricing or royalties information.
And my book's detail page has been stuck for well over a week with a label saying "Recent Changes to your Book may Require Several Hours to Take Effect".
I emailed Google support several days and haven't heard back.

Any other writers out there? :)
