Why did the banking screen change. now only shows bank balance not QB balance for that account.

Thank you for posting here in the Community, @andrew80!

Several customers received an update to their QuickBooks Online account, including the Banking page. I can see that having this information on the Banking page allows you to take a quick look at your bank and QuickBooks account balance. Meanwhile, you can go to your Dashboard. Then, from the Bank Accounts section, you'll see both the bank and QuickBooks balances. 
 

You can also read through these articles to learn more about managing downloaded banking transactions and receipts:

• Categorize and match online bank transactions in QuickBooks Online
• Capture and categorize receipts and bills

Lastly, I'd like to let you know that our developers are constantly uncovering and considering new ways to improve the program. To be updated with our latest news and enhancements, you can visit our QuickBooks Online Blog site.

I'm always here if you have other questions or concerns, andrew80. Have a great day!
