Track and Trace, Government IT fails again! Options

[Mr Brown]

Does any Government sponsored IT development ever work properly? It seems that the much delayed App doesn’t work on older (in some cases by 18 months) ‘Smart’ phones. Still, it’s only little people disadvantaged by this. Government for the few takes off!

"What should I do if I get a notification saying that I’ve been in ‘close contact’ with someone who has coronavirus (COVID-19), but I do not believe I have?
The app will send you a notification if it calculates that you have been in ‘close contact’ with someone who then tests positive for coronavirus. The alert will not identify the individual in any way. A scientific calculation, using an “algorithm”, has been developed by NHS doctors and scientists to work out which app users are ‘close contacts’.

‘Close contact’ generally means you have been within 2 metres of someone for 15 minutes or more. Read more about how the risk scoring algorithm works.

If you have questions about how the advice applies to you, or are struggling with self-isolation, please call 111."

We're expected to trust a government algorithm?
