I'm sorry to be negative but no banking app, especially provided by one of the major banks, would ask for a 'value' to be typed into a login box - it should be clearly labelled 'User ID'. It could be that the app has been upgraded or that the app has not been optimised for your browser but unlikely.
Your banking User ID is part of your online identity and should be kept private. I would at least close my browser, then re-open it and try typing in the bank website again. Check for the padlock to show the connection is secure and if you get the same screen, I would contact the bank by phone and ask for their advice. At the very least, you will have reported a problem with their app to Lloyds.
