Just after upgrading it did not work so I changed the settings and it started working. But after a reboot it reverted to not working and now I can’t make it work.
I created another user and it also does not work for the new user.
I’m having the exact same issue. I even tried changing the settings to Sleep after inactivity and that doesn’t work either. Seems no power management settings are working anymore.
BTW, thanks for the tip on the keyboard shortcut. I’ll use that until they fix this.
