Catalina and Adobe Flash update

You may need to do one or more of the following if still having issues?

• install (reinstall?) Flash player from Adobe's web site (if using Catalina, use the most current - see above per -DaveD)
• look at menu -> Safari / Preferences / General, left nav panel at the bottom Plug-ins, see that Adobe flash Player is checked
• on the right nav panel, see that the web site you need is allowing Flash

Might be some other issues, i.e., if you're using any 3rd-party anti-virus or malware apps. If it was working before, do you know what might have changed? Most commonly, Safari will notify you at the top of the browser if there's something wonky. Anytime I run into a similar issue with a web site, I use current version Firefox, and the web site then almost always plays nice.

Well, there was nothing helpful on the Adobe site, however I found this from "Apple's Safari team" from 2017 on a Webkit page that explains a lot: https://webkit.org/blog/7839/adobe-announces-flash-distribution-and-updates-to-end/

I then downloaded Flash Player from Adobe, installed it, and enabled it in Safari Preferences under the "Websites" tab ("plugins" in the left-hand column). I then went back to one of the sites that contains old flash content, clicked on the "click to run Flash" place holder, selected "Run every time" button from the dropdown, and voila! Flash content displayed!

Turns out the Level 2 Apple Care support tech, who insisted "Catalina does NOT run Flash as it is 32 bit", who insisted "there's no one else to check with because [he] was the highest [I] could go at Apple", was full of crap, which I am finding far too frequently lately.

FWIW, you can also check System Preferences > Flash for updates. Assuming you have Flash installed of course.
