Re: Source as requested.
From the same article:
If the app tells you to self-isolate, you're supposed to, but it is not a legal requirement in the same way as when you test positive for the virus or are contacted directly by NHS test and trace.
In other words, if the app tells you to self-isolate then you should but there's no legal requirement for you to do so (sadly, we can't legislate against stupid). However, if you are contacted by one of the Serco script-monkeys then you're required to self-isolate on pain of impecunity.
As ever with this bunch of cockwaffles, the devil is in the detail.
