I received a brand new phantom 4 pro and I haven’t been able to use it because of a “barometer issue.” It happens everytime I turn it on and won’t let me take off. Please help!!!! Thanks

at least did you try to upgrade firmware or refresh? That's what I'll do in this case

If it is brand new, then don't waste your time here, take it back to where you bought it and ask for an exchange.

Please try to refresh the firmware of the drone via DJI Assistant 2, then calibrate the IMU. If it persists, please contact the dealer and ask for an exchange.
