P4PRO, no crash, lossing consistently GPS mode in midflight to ATTI.
From 12-14 to 0 in one second, no come back in GPS mode even after many minutes.
Only ATTI. Good magnetology. The problem is in each location.

Hi, we're sorry for the inconvenience that it caused. I would recommend checking the remote controller to see if it's on the P-mode. If so, try to calibrate the IMU and compass to see if that would help. If the problem persists, you may download the DJI Assistant 2 using this link: https://www.dji.com/downloads and refresh the firmware into the latest version to see if there will be changes. Please keep us posted on the latest progress. Thank you for your support.
