I understand, "Out of Stock", but why is the controller IN stock for many countries and not for US, Canada, etc?  

I've asked the same question still no answer.

Hi, thanks for the inquiry. The smart controller is out of stock due to the high volume demand in the US and Canada. No worries, we're doing our best to provide more stocks on our store for our other customers to purchase and experience this newly Smart controller. You may leave your email on our store for you to be notified once this item is available, or check it on our authorized reseller using the link below. Please keep us posted on the latest progress. Thank you for continued support.

It has been available in Canada. I have one, however it was not long and they were out of stock again.

It was out of stock middle of January when I was in the US.
I asked for notification upon availability. When I received that e-mail I ordered right away.
A couple of days later it was out of stock again.

Ok, I decided to order from one of the authorized dealers, but they are telling me they cannot get the controller either for at least 2 weeks.   I will keep checking other retailers, but this all seems odd.  The price point is too high for it be leaping off shelves.  It has to be supply issues.

Come on DJI... you are the reason I have a drone business.... help me out here.   I need to ditch the phone interface!
