Maybe I’m doing something wrong, but I created a Credit Note, and referenced the correct invoice and amounts, but this didn’t affect the Bank Balance, I’ve temporarily manually added a placeholder transaction in order to get the bank to balance.
Shouldn’t the Credit Note automatically create a transaction entry?
A credit note does not record actual payment of money to the customer, but only adjusts the customer’s balance in Accounts receivable . A credit note can be created regardless of whether the customer has yet paid for the goods or services.
No, definitely not. A credit note is certainly transactional in a financial sense; it is the reverse of a sales invoice. And, for completeness, by delivery order, I assume you mean delivery note. Manager has no delivery orders. A delivery note is also transactional, affecting status of inventory item quantities, though not affecting financial information.

However if you read the preceding 2 opening sentences in the referred Guide then you would have noticed as also explained by @Tut that it is definitely transactional but not with bank or cash, ie but with:
A credit note records the return of goods by a customer or a credit adjustment (refund) to a customer’s account for goods or services previously invoiced. It makes all necessary corrections to inventory and income accounts.
