First let me say I have a DJI Mavic Air. Having an issue trying to calibrate the vision sensors through the DJI assistant 2. After I click through the 3 training slides, when I get to the actual calibration screens, the "green box" is square as it should be, but the red square is like "cone" shaped (bigger at bottom than top), so cannot line the two up. I have tried to adjust my screen on the pc, I have uninstalled and re-installed the DJI assistant 2 app, I have downloaded and installed the latest firmware, but still have the same problem. I can still fly but kinda nervous when the DJIGO app, tells me this calibration needs to be done. Any help would be greatly appreciated.
