My ongoing confusion after updating to Buster and CPU load

Ok. I thought I had done that. (Moving on)
I copy the flows.json and flows_cred.json file from their backup.

The flows.json has gone from 1.3 meg to 2.2 meg in size.

From New version of NR, lost in `settings.js` file - #3 by Trying_to_learn

That's a tricky point.
Same machine.
Said machine died and I rebuilt it.
So it is going back onto the same machine, but a different build of NR (and O/S)

I tried doing what I understand is needed to be done, but it doesn't/didn't work.
(That was a long time ago)

Well, I hope not. I stopped NR, put the new files in and started NR.
Lots of scrolling as it started which was kind of normal but some of them were new.
I didn't screen shot it.
There couldn't be any hidden tabs as the NR version was too early.
