I realize that this is mostly out of your control, but as far as timeframe for exiting "development status"... are we thinking that it could be any day now? Or is it likely it may be months away, or never?
Well, as it took 2 weeks and several emails originally ..... the answer is "I don't know". Sorry.
We've had much better communication with Amazon lately (eg, they're actually replying).
In fact, right now, the emails are about the exact API usage and clearing up some functionality, between Alex and Amazon. So, things are looking good.
If you check the first post, Alex has updated it with the latest responses.
