Catalina is definitely the most badly broken release in the last 10 years. I can't get Chrome desktop notifications to work anymore, but the worst thing is that all my Apple Music playlists have disappeared from my iPhone. They do exist in the Catalina Music app, but not on the phone where I need them. I suspect it's because my iPhone 6 isn't supported by the latest iOS release and there appears to be some iCloud version incompatibility that was triggered by Catalina. The iPhone Music app has crashed a few times as well. They do warn me of just such an incompatibility when I open the Reminders app (which now has a far more convoluted user interface for no apparent benefit). I get the feeling that my decision to just keep using my iPhone 6 until it's not longer good enough will be difficult to sustain. Catalina also randomly stalls for a second or two and some mouse clicks just don't register for a long time until they eventually do. This seems to have gotten a bit better now so I'm hopeful that it was related to uncached data.
