Track and trace seems to have a wee problem .

I was reading the government web site yesterday thinking I should down load the App . About 3/4 of the way down the instructions it said the track and trace which I believe should be starting today , the App wasn't ready . It was called the NHS App , is that a sly way of distancing yourself from the App and blaming the NHS ?
Any way it isn't going to work particularly well without the App.
