Undo Auto Layout

Can anyone tell me where the minus went to undo auto layout in the upper right corner?? I know there is a hotkey for it, but why did it just disappear.

Mac: Shift + Opt + A.
Windows: Shift + Alt + A.

The Remove icon (the minus sign on the Property panel in the Auto Layout section) is still in its place.

I wish I could attach a picture, but It’s not in my file.

Have you tried reloading the tab or restarting the app/browser?
