Home Sharing Broken on Catalina

Is anyone out there successfully using Home Sharing from a Mac on Catalina? Got new Mac mini and Catalina is one train wreck after another. Never mind that Finder regularly stops connecting to network drives… or Speech voices don’t work correctly… still on 10.15.5.

I have difficulty connecting to my Home Sharing library from iPad and iPhone, but not Apple TV. But the real problem is that no 4K movie I’ve ripped is shared at all! I see this mentioned on Apple Support discussions once last fall, with just two posts. Seems like a bigger issue. Anyone?
