Hi @MichaelSowa
Welcome to QuickFile 
The QuickFile chrome extension will generally work only for the business accounts and not personal. Unfortunately, there are many limitations with the way we do it, but it’s the only possible way of doing so until the banks implement an API (you’re welcome to prod your bank about getting one of these ;))
Have they changed their interface recently? When you login, some banks will download them automatically, others will need the ‘Export to QuickFile’ button to be clicked.
The software will try to link up the banks by using their account numbers and sort codes. They will however, all appear in your dashboard for you to check before anything is added.

I hope that helps?
