I signed up with the Test & Trace app almost as soon as it was launched. I set up my Bluetooth to scan proximity to others and I had also taken care to scan into any venue I entered.
However it did not tell me to self-isolate, it said my proximity was not long enough.
I recently read that the sensitivity of the app was set lower than it could have been. Meaning that having been near to an infected person is not enough for the app to advise the user to stay at home.
