Auto-shutdown Domain Joined Computers at specific time (Issue)

I have implemented a GPO and linked on computers/users OU. All machines are DC joined.

But the problem is that GPO is not taking place on computers, even though not showing in GPRESULT /r command.

I want to auto shut down computers daily at 8 PM, as well as if the computer is idle for 1 hour.

I also ran gpupdate /force and it was successful and even restarted the computer, but still GPO is not applying.

Please suggest if I am doing something wrong? or suggest any better option via GPO?
