Mix history/undo not working in Cubase 12?

Hi I’m learning my way around Cubase 12 and following a course. They are showing the mix history and mix undo buttons in the Mixer, yet when I change any parameter such as volume etc. nothing is recorded in Mix History and I cannot undo.

Am I missing something?

Thanks

The only thing I can think of, assuming for example changing the mix console volume slider, is if you move it from one position to another position too fast.

I’ll assume you are waiting a second or two?

yeah I was waiting, and trying everything. For some weird reason now it works. I just moved on and did a lot of other stuff so I’m not sure what changed! I hadn’t saved the project before, and now I have so I wonder if that has something to do with it

Sometimes this also happens to me, its very random. I then work on a new project and the history stays empty. Happens about 1-2 times a month, and could not find a way to reproduce it unfortunately…
