Re: Useless systems
You should try again. I believe they've sorted this out.
It's an internal/external account number issue. The translation wasn't working. Mortgages (unlike most of their products) aren't hosted on the core Proteo system. So need account number translation when interacting with common core platforms (like digital).
However, I believe that under the Lloyds architecture, if you have a mortgage and no other Lloyds product you can't see your mortgage on line at all. This is changing at TSB - so long as you can register!
