I am interested in buying a Mavic 2 in conjunction with the Smart Controller. But for weeks there is no stock in the official DJI Spain store.

What happens? Why are there no units in stock? Is there a serious problem that DJI is solving with the Smart Controller?

Just try and buy the Smart Controller by itself....
You can't.
Looks like they did not do enough on the initial order from suppliers....

Hi, we're sorry that the Smart controller is currently not available. This phenomenon probably due to the high demand for this unit and our team is working on this situation to provide the stocks as soon as possible. You may provide your email in "IN STOCK REMINDER" section for you to be notified once it became available. In the mean-time, you may check if you could possibly purchase the Smart controller to our other dealers. Thank you for understanding.
