Thanks, Col.

So confirmed that Big Sur has the same problem, both on newer and older 
Mac's.

Issue seems to have surfaced somewhere around Mojave.

Most folk from various fora suggested Location Services were to blame. I 
turned all of mine off, no joy.

A friend of mine in Malaysia noticed an improvement when he disabled 
Handoff between the Mac and all his other iCloud-enabled devices. But 
that didn't work for me.
