Hi there, 

The Bank Feed is an important time-saving tool in QuickBooks Online. If you've connected a bank or credit card account with your QuickBooks and you're noticing that your transactions aren't downloading, there's a few steps you can try to re-trigger the automatic uploads. 

Take a look at this article: What to do if bank transactions won’t download. 

The first step is to try manually downloading your latest transactions. Next, the article gives an overview of how to check your bank's website for notifications or issues on their end. Step number 3 in the article reviews specific error messages and how to resolve them.

I believe this article will get you back on track. If you've tried all the steps listed there and you're still unable to update your latest transactions, let me know in the comments below. I'm here to help. 

Have a great day.
