Glad to have you here in the Community, finley-finleygho.
It can take up to 10 business days to activate a direct bank feeds connection in QuickBooks Online. Let me provide reasons why a direct bank feed was not approved.
You can verify the following below:
Has it been more than 10 days since client form was submitted.
Signatories on the client authority form is not clear or does not match with the bank.
Company ID, BSB and account number are incorrect.
Client authority form was not set to Intuit SISS.
Furthermore, if the bank account is also connected with Standard feeds connection, and found out the bank feed is not updating. You can perform an edit sign in info to refresh the connection. Here's how:
Click on Banking/Transactions tab.
Click on the Pencil icon of the bank account affected.
Click on Edit sign in info.
Enter your banks log in details, make sure to manually type the information.
If it has been more than 10 business days from the time you sent the client authority form, I suggest QuickBooks Online Customer Care (AU) for them to further check your account connection.
