I've been getting the old "It’s not you, it’s me" for weeks now.
One day it was working as usual, the next it wasn't, and never has since early Feb.

I've no confidence that if I identify myself to it, or hand over money, it would start working.

I have joined reddit especially to progress this. Can anyone tell me where I can turn next?

I think it is a bot defence of some kind. Please only answer if you know of something that has changed recently - I don't want to be walked through checking all the things at my end which I know didn't change in the relevant time window. I know people love to do that, and Copilot did too - I miss him/her!
