MA2 Permanently Detecting Obstacle Behind, Cannot Reverse

[cosmiclemur]

Hey all. Mavic Air 2 in use for a few years now. It operates beautifully still, except one strange issue where it's constantly detecting an obstacle behind. The warning on the screen always shows a red line, when there is no obstacle behind it. When I try to fly backward, it just stops and starts again and again. I have to turn the drone around and fly forward instead.

I've made sure the sensor is clean and all my software is updated, but I fear the rear sensor may just be broken somehow? There is no visible damage to anything on the drone.

Anyone else had this issue?

The only thing I have a niggling worry about is if the drone detects that they are bust it might ground the drone.
