Bank tagging creates new invoices (duplicates)

To put it simply - it doesn’t know which invoice a payment could relate to.

If you have 2 or more invoices for the same supplier, same date and amount, it doesn’t know which one it should update.

The best way to use them initially is to switch off auto tagging so you can see what action it will take, but you would confirm it before it processes it.
