After the update, the problems of false obstacles have increased. I wrote to DJI who replied in this way:
note They have increased so much that I had to return the product because it was defective (unusable)

Hi , please try the below troubleshooting steps which may be helpful to resolves the issue.
1. We recommend that you first update your aircraft to firmware version v01.00.0100, which can resolve some known false obstacle avoidance alerts.
2. If the false obstacle avoidance scenario is known to be unfixable, you are advised to avoid such scenarios.
3. If you fly the aircraft at high altitude immediately after purchase, false obstacle avoidance alerts may occur:1) Refer to template 2;2) It is recommended that you perform low-altitude flights for 1–3 minutes in an open area after takeoff to trigger self-calibration.3) After performing this procedure, subsequent flights should experience fewer false obstacle avoidance alerts;"
