niggles logging-in with the new system

Powered up this morning, opened IE11 and, as usual, the first thing I did was to open my Identity Safe (Vault). Instead of the usual log-in, it was the one requiring me first to log-in to my Norton account. I couldn't - my paper copy of the log-in details was unavailable so I clicked on 'forgotten password?' and it said an email was on its way.

Then I went to open my Outlook account - I couldn't, because the Vault was closed and the log-in details were on the same piece of paper.

I've solved this by recording both log-in ID/Passwords in other places - diary, calendar etc. so it won't happen again.

I restarted my laptop and this time the usual Vault log-in screen appeared.

So, two questions:

(1) Why does the Identity Safe log-in screen occasionally change to requiring Norton account log-in details?

(2) Would it cause problems for Norton (and for me) if I remained permanently logged into the Community?

(I'm not sure whether or not this is an Identity Safe issue or a log-in issue.)
