@John_Charnock - Can I just check, were you prompted to set up an Open Banking feed? If not, check the logo on the bank statement view - it should show the logo of the bank. If you only see an icon, you will need to set the bank in the settings first (More Options >> Settings).
@ABDB - We are aware of an issue with the Santander Open Banking feeds which was affecting all users (not just on QuickFile). However, this has since been rectified.
