Does undo automation work?


I’m having serious troubles with the automation undo. I can’t find any information about this, does it work? Well it doesn’t here.
I’m on the latest “everything” 9.5 and so on.
Here is the scenario: Automating volume on a track, and change my mind, hit command Z, nothing happens. Goes to the Edit menu, and undo redo is greyed out, goes to mixer Mixer History, and find the movements and delete them goes back to arrangement and the fader movements is still on the track.
Any help much appreciated.

Hello guys,
Someone must be able to tell me if Undo works with automation!!!
