Working fine here, but I don't have a lot of background stuff running. I also have Norton 360 and with that WC works.
I suggest doing a clean install, that is clean out all junk running inthe background before you take the leap. Really, though, I can't see a lot of change with Catalina like I did with Mojave. Sure they split iTunes up into 3 apps but I just don''t see an improvement.
Perhaps later stuff will come along and this is the platform. My biggest angst is that my scanner program for my all in one, doesn't work and the software comapny is being a dick about it. but I willl find a solution.
