System Tray Problems in Win10 Home v. 2004

I am using Windows 10 Home, 64-bit, with a laptop connected to the
Internet via Wi-Fi. I recently upgraded to the 2004 version.

I just noticed that if I click on the Wi-Fi or Clock icons (both
located in the System Tray), nothing happens.

Typically, clicking on the Wi-Fi icon would show the available Wi-Fi
networks and some tiles called Wi-Fi, Airplane Mode, and Mobile Hotspot.

And normally clicking on the clock would bring up the calendar.

Plese note: The laptop is able to connect to all the _registered_
Wi-Fi networks. I don’t have a problem connecting to the Internet so
long as one of the registered Wi-Fi networks is available. But the
problem would be if I need to connect to a new Wi-Fi network.

All the other icons in the System Tray seem to work ok.

Has anyone else experienced this and found a solution?
