It probably doesn't take many delays along the ch.ain of track and trace (test, contact list, phone calls, contacts tested, results) to render the system far to retrospective to be of any use.
Plus how many on here have downloaded the NHS app? If you haven't (I'm not judging you) then simply, you've really forfeited your right to moan about it.
I downloaded it and moaned about it
I know there are those that moaned about the delay till the cows came home and then decided they would not download it, go figure that one out
