Cinemachine recorder button not working in 2019.2? Cannot set camera key frames?????

When I create an animation track and put my camera in the animation track the recorder button doesnt work??? Using Unity 2019.2.

I have the same problem!
I want to keyframe a GameObject.
(And the target is Component other than Transform)
But I can’t press the record button on the timeline.
It is grayed out.
Unity 2019.3.0b3.

Am I making some rudimentary mistakes?
