Hi, I am having some problems with my P3. My app shows all the required information as normal but no feed from the camers is shown, took some random pics with the black live view screen and nothing was stored to the sd card. I tried both IOS and Andriod devices and same result. I flew the previous day with no problems also i did not do any new updates to firmware since my last flight. Can anyone help
