I know it is difficult for US based companies not to think US Centric, but is there any chance you could set up a separate account for your US customers & perhaps for International. Ideally we could get per-country feeds (perhaps you could have a stream per country & build a custom contribution app to still let you manage it centrally). Even as a starting point keep this account for the US, and set up a "Google Play International" for the rest of us.
I'm afraid to say that at the moment you just manage to disappoint your international customers with announcement after announcement that's US Centric.
At the end of the day, your current approach will only result in people from around the globe unfollowing you (as I'm about to), which I'm sure is not your aim. Perhaps look within your organisation or to other organisations with assistance in your digital marketing strategy. This one's not working.
Locally for me, I'd love to think that +Google Australia
could pick up the slack, although I realise that organisationally that's unlikely to happen.
