I updated the RC and aircraft firmware but I am still getting the warning and the aircraft is unable to fly. Any idea how to fix it? Thanks

Hello and good day Euri. I am sorry for the troubles that you are having issues with your DJI Mavic Air. I would like to ask if the drone experience any incident before? Did you try to restart your aircraft multiple times to see if the error message would disappear? If the problem persists, I would recommend contacting our support team using the link below for a further evaluation of your unit. For additional information, the repair fee would depend on the outcome of the damage assessment and the warranty of our DJI Product. Should you have further concern, please keep us posted. Thank you for your support.
