The first time I posted this question, there were problems with upvoting, because of an "unexpected response from server," so this is a re-try.
The "do-over of 2020" refers to the "happy new year 2020" box at the upper right corner of the screen.
Update: I tried posting an answer to this question, but I got the "unexpected response" again. :-(
Nope today Jan 27, I cannot upvote either Tink's Q or your answer, Dan!
Nope I cannot upvote your Q here, Tink...but I saw on the Internet the computer geeks are working on an "uninstall" for the year 2020.
