Problems with FW are gone in my case. They were caused by my tablet : Huawei MediaPad T3 7. It is no more compatible with the new FW for Mavic. It is somehow annoying. You have a product and suddenly you need to buy a new one, because it is no more compatible. Other surprise was that the FW update for remote controller should be with the App. It is not possible with DJI assistant 2. It was not a defect in remote Controller either. Is there an "official" list of compatible Phones or Tablets? German DJI technical suppurt said to me the Hawei P10 plus is not recommended. It is on the list of Mavic Air Pilots. It was the model I wanted to buy.
All this is a total chaos for me.
