You got it

They do work individually but, this is not the case when you cross from say, England to Scotland or England to N. Ireland.
You can start again in the "new" country but, if your work / travel involves crossing the borders there is a problem.

Perhaps I should have gone into more detail with the original post.

Anything to say about the latest on our "world beating" test and trace debacle.
Not only have they missed 16,000 positive tests but, it seems that even if you live with someone who has downloaded the app and has tested positive, you are informed that you're still good to move around "freely".

Come on our kid, pick the fault with this one.

This is not the first major issue with an Excel spreadsheet - sadly their use in high level projection outcomes is far too prevalent - a case of where a little knowledge is dangerous.

Are the NHS still using very old versions of Windows?

The NHS is on Windows 10 now.

I could understand that on critical equipment e.g. MRI scanners but not normal day to day activity - surely

It's crazy to blame excel for the problem.
Who wrote the bloody software and who doled out the contract to such an inept organisation.

There is a common theme running all through the pandemic response and clearly, those "in charge" are just not up to the job.
Our PM proclaimed IN JUNE that we had a WORLD BEATING system.

It the Tories were in charge of broadband, we'd all be on dial up and being told just how good it was

35 organisations are listed as “data processors” involved in the NHS Test and Trace system but only 4 are NHS bodies. 4 are Lighthouse Labs. A further 4 are Public Health England bodies and another is the Ministry of Defence. The remaining 22 are private companies.

The response to the pandemic is indeed under the governments "control".
They are ultimately in charge of the procurement of everything, form aprons to vaccines etc and with regard to the "test and trace", it's been oversold and under delivered since it's inception.
Now, I'm fully aware that Boris doesn't write the software for the system - just imagine if he did but, he was quick enough to take credit for it's roll out and by god, he has to carry the can when it goes wrong.
All of the glory but, none of the pain.
So quick to wave the flags and yet so damn slow, even hiding when the shmidt comes down.

My lad is a graduate software engineer and he explained exactly where the problem was with using excel for this application.
He said that they had covered this type of issue at GCSE and A level.
Now, if a lad in his early 20's knows the limitations of using excel to collate and store this type of information, just who the hell have the government used for their software development.
You will no doubt recall the earlier issues of surrounding the communication (or lack of it) between mobile devices ?

If the PM hails the system as "world beating", at the very least, you would expect it to work and work reasonably well.

I wouldn't expect Boris to be personally be placing orders for PPE or writing the software for the test and trace system.
We can take the view that they should sort out the problem with their "supplier" or, take your view that, it's not actually their fault and lets put up with more lies and failings.
The one certainty is that whoever signed off on some of this stuff is not up to the job.

Over sell, under deliver, has been the theme of the Bojo reign and you seem happy for it to continue.
Next up Brexit

When did the people running schools take an elongated break
