I'm here to make sure you're able to get the most updated banking transactions in your QuickBooks Online, jono-hare.

In order to get transactions updating again, you can try updating it manually. 

Here's how:

1. Go to Banking from the left menu.
2. Select the Update button in the upper right-hand corner.
   
3. Wait until the update is done.

If you're getting the same result, you can sign in to your bank's website to check if there are any alerts or notifications that may block QuickBooks from downloading new transactions. Please refer to this link on how: What to do if bank transactions won’t download or there's a bank error.

In the meantime, you can upload the transactions manually to ensure the account is up-to-date. Download the data from your bank then map the transactions in the following supported formats or  file types:

• Comma-Separated Values (CSV)
• QuickBooks Online (QBO)
• Quicken (QFX)
   

For the information and steps on importing these files, see this article: Manually upload transactions into QuickBooks Online.

While I don't see any active investigations regarding Nedbank yet, I'll be sure to keep a lookout for incoming reports throughout the day.
 

Visit me here again in the Community and keep me posted on your progress with this banking issue. I'm determined to help you succeed.
