Let's resolve the issue you're having with your bank account to get your latest transactions, @usertoksikumelo. I appreciate the efforts trying to sort the missing transactions out.
If you're referring to non-downloaded transactions, QBO is dependent on what your bank shares with us. This means when you link the bank, it only brings in 90 days of transactions.
Since you need more than that, you'll have to upload the missing data from July-August into your account using a CSV file. After that, you have to import them into QBO.
If you want to know more about the process, you can refer to these articles:
To categorise and match missing transactions after importing them, you can refer to this link.
