NO CHOICE for Auto Takeoff: So I update the app to 0.9.2, update the firmware to 1.2.0.16, calibrate the compass, and calibrate the IMU. I restart everything, start the motors and hear the app tell me "The home point has been updated... TAKE OFF"

The soft button on the left side of the screen that I WOULD press if I WANTED auto-takeoff is now and auto landing button. Has DJI forced auto takeoff on us?

Its because you started the motors, once you start the motors it assumes you are taking off manually.  Had you not started the motors you should have had the option to auto takeoff.

Agree with above post.
before auto takeoff, the drone shall stay on the ground and motor not working
