I cannot find out how to use AE lock on my mavic air. Tapping around on the screen I once got the box saying "Auto Exposure Locked" but not sure how I got there. I can't seem to find it in the manual either?
Some pictures of the DJI Go 4 app show an AE lock button in the top right corner of the screen, but the air doesn't seem to have this?

Would be nice if someone can explain me how to enable and disable AE lock with the mavic air. Thx in advance!

When you see the "AE locked" popped up when the AE is locked. Just tap the center of the live screen to enable AE lock. That's it.
