Hi @Michael_Oborne,

ok @Michael_Oborne, thanks.

bought 3 units from UUUDrone Store, trying to update, arguing with the seller that the key was on the box . I am 4 days in waiting for an answer. Even if the key was or not on the plastic now is gone. Customer support from them is very bad. Any other way to get the key ?
