MacOS – Today panel is white/disabled and unusable since upgrading to Sierra

macosnotifications

The right side panel for me, is white and disabled. I do not see any settings that would cause this behaviour. How can I return to the working version of this panel? In particular, the World Clock widget is important to me and I currently can't use it.

The problem has resolved itself. Apparently the solution is to wait.
