I can't log in. Tried to login, got a message saying there was a security issue with my account and that my password needed to be reset.

Tried logging in with the new password and am now seeing a message that says I can't get logged in and if the issue persists, my account is locked and I'll get an email. No email so far.

I was logged in on the nx page, but had to log in again when I went to use the avios estore, which is on the old website. That's when the issue started. Not sure if this is an IT issue or there's a genuine problem here. I'm still logged in on the app.
