Of course, you have every reason to demand that a product sold with certain functions must fulfill as described, but I think that here there is a misunderstanding that not even Parrot is able to explain, according to all the information, white-paper,manuals indicate that the rectilinear photos are in 16 MP.
At one point how was possible that we were able to use 21 MP? Being that it was never designed for this resolution?
The problem is Parrot, they never explains its errors leaving users in a state of abandonment, as well as in many other problems that occur creating more confusion to the users
Personally through European consumer law I made a claim for the total lack of professionalism of Parrot to the point that they have simply ignored the claim of the lawyers in France without response
We need here in Europe a drone advocacy like it was mention in another threads
