Thanks for contacting us, User012.

I appreciate you for contacting our QuickBooks Online Technical Team to get help with missing transactions on your bank feeds.

Usually, you need to manually download your latest transactions when this happens.

1. Go to the Banking menu.
2. Select the blue tile at the top for the bank account you want to update.
3. Click Update.
4. Go to the For Review tab since this is where QuickBooks puts successfully downloaded transactions.
5. If you find the missing transaction, categorise it into an account. Transactions won’t show up on your books until you categorise them.
6. Next, go to the Reviewed tab.  
7. Look for your transaction and review the Added or Matched column.

Please see the attached screenshot below on how transactions are sent nightly.

If you're still unable to see those entries on your bank feeds, the issue may be on your financial institution's end. What you need to do is sign in to your bank's website to check this. 

When you're able to log in to their website:

• Check your account page for messages, notifications, or alerts. Any display or sign-in issues on your bank’s website can potentially block QuickBooks from downloading new transactions.
• Check for any announcements about new security requirements.
• If everything looks good, go back to the Banking menu in QuickBooks and follow the manual update above.

I've added this article: What to do if you can’t find downloaded bank transactions for detailed steps on how to find missing entries.
