Why does my Credit card bank feed mis some transactions.?

Hi there, @huwrrowlands.

I'd like to help and find those missing transactions. May I know the name of your Credit card account? This way, I'll be able to check here on my end if there are any related issues. Additional details are appreciated.

Nonetheless, there are a few possible reasons for missing credit card transactions on your bank feeds. These are the following:

• Depending on your bank or financial institution. Some banks will show the transaction on their website but won't download it until it is posted. 
• If the missing transactions are the most recent ones, wait at least 24 hours in case your bank doesn't make them available immediately. 

In the meantime, I'd suggest updating your account to have the latest available transactions. This will also refresh the connection between your bank and QuickBooks. Let me show you how. 

In your QuickBooks Online (QBO) account:

1. Go to the Banking or Transactions menu.
2. Select Update.
3. Click Update Now. 

Furthermore, here's an article you can read for more details: What to do if bank transactions won’t download or there's a bank error.

Let me know if there's anything else you need help with. I'm more than happy to assist you. Have a great day and keep safe!
