I've got some solutions to help update your payment transactions on the Banking page seamlessly, @hayk-brella-io.

To start, let's perform some troubleshooting steps to fix this. There are times that the browser is full of frequently obtained page resources, which causes some errors or unusual responses. Let's start accessing your account using a different or a private browser. You can use either of these shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

Once the transactions are updated, go back to your regular browser and clear its cache. This is done to speed up the process next time you do a transaction in QuickBooks Online. Also, an alternative way is to use other compatible browsers.

I also suggest contacting your bank. You can ask them if there are new alerts, system maintenance, or policy changes on their end that cause the delayed updates. 

May I ask if you received an error message when trying to do the update? I appreciate any extra information you can give, and it will help us isolate the issue and provide the best solution.

After fixing the said issue, you're now ready to categorize and match your entries. This helps avoid duplicates and make sure you're placing them into the right accounts.

Fill me in if you have other banking concerns with QuickBooks. I'll be around to help you again. Keep safe and have a good one.
