Sidecar with iPad Pro 6th gen

Hi, every time I try to use sidecar over bluetooth / wireless, my computer says "A miscellaneous error occurred (-455)."

I'm a little peeved bc this is a $1400 piece of equipment that fails right out of the box. I've check to make sure that all the settings are checked (bluetooth, wifi, and handoff being turned on and on the same network, and being signed in on the same Apple ID).

I know I can run stuff over the USB cable as well, which is what I do, but seriously Apple... if you market a device as working "smoothly " with a wireless connection, and these devices fail right out of the box, I lose trust quickly.
