Folks: My mini 3 pro with RC N1 performs well in all respects except one. When I push the icon on my phone to change to portrait mode, the camera rotates instantly. However, I cannot return to landscape mode by pushing the same icon. Nothing happens. The only way I can get back into landscape mode is to land the drone, turn it off, then turn it back on again to reboot. Any I doing something wrong or is my unit misbehaving?
