Thanks for replying back here and providing the name of the bank you're having an issue with right now, @bbalu. Allow me to assist you further and offer some steps to perform so we can rectify this and be able to help you keep going with your tasks.

Since you mentioned that the transactions are being displayed and only the credit card balance isn't updating or showing as $0, we can perform these troubleshooting steps to check any issues and update the connection. Here's how:

1. Go to the Banking menu then select Banking.
2. Select Link Account beside Update. Note that we won't be adding an account, we just need the listed URL.
3. Search for your bank and select it.
4. Copy the URL listed for your bank and sign in to your credit card's website using the copied URL.
5. Select the tile for the bank account.
6. Hit Update.

If you're able to sign in, it's a good sign that there isn't a major issue. Next, I'd recommend checking the following:

• Look for messages, notifications, or alerts.
• Look for any display issues on the website.
• Check for any announcements about new security requirements.

If everything looks good, go back to the Banking menu of QuickBooks then hit on the Update button beside Link account.

However, if the credit card balance is still showing as $0, I'd recommend getting in touch with our Techincal Support Team so they can go ahead and check on your account in a secure environment using their tools and determine the root cause of this problem.
