That indeed was the problem. Thanks. It is working now. But has anyone figured out how to get Avast to turn it back when once it turns it off?
We don't really know if Avast is the problem, but so far no one has complained who doesn't have it. That being said, in the Avast settings (open it, go to Menu , Settings, Components, scroll down the page until Performance, Do Not Disturb Mode, then Customize) there is a setting called "Silence notifications from 3rd-party apps". By default it's on, I turned it off. Maybe it helps.
Now you have someone reporting who doesn't use Avast.
I'm on AVG, latest updates to all pc packages.
Focus Assist running almost 24/7?
When open notifications pane, nothing is there?
