I just got a ERROR 27 GPS not calibrated, or magnetic field interferance. Please calibrate GPS again in good condition.
I just upgraded to 3.12, did an advance IMU calibration, took it out side, did a compass calibration and now it will not lock a full GPS signal and I keep getting that error when plugged into the assist.  Any help?

Did you do the IMU calibration on a metal desk or have any metal around it?

My PC Desk is metal and did it near there, I'll try and on the wood floor

Right,  the metal probably has affected the calibration.
