Weather widgets on iMac suddenly quit working

Please reset the NVRAM and restart in Safe Mode. If the resets do not help, please contact the widget's developers.

Instructions for the resets are in https://support.apple.com/en-us/HT204063 & https://support.apple.com/en-us/HT201262

I have also noticed that the "Weather widgets" are not working. In my case, I have confirmed that they are stock Apple Weather Widgets, and I don't think that resetting NVRAM/PRAM, or using Safe Mode will be effective. I may try Safe Mode when I have some time, but doubt that it will make a difference.

Weather Widget displays have returned to normal function without any action on my part.
