Logitech MX Master 3 for Mac

The connectivity issues for Big Sur remain whether with USB or Bluetooth, and there don't seem to be any reliable answers. That a mouse can't even connect via USB is incomprehensible. Does the problem lie with Logitech or with Apple? When will there be a driver for Big Sur 11.2.3? Should I just return the mouse now and wait for Logitech - Apple to Get Act In Gear?
