Why are my bank west accounts not updating all of a sudden?

Hello, kerriecauvin-gma. 

I'd like to make sure that you're able to update your bank account and be able to categorize the transactions. First, let's manually update your bank to bring the transactions to QuickBooks Online. 

1. Go to the Banking menu.
2. Select the bank account you want to update.
3. Tap Update.

Second, If the same things happen, let's isolate this case by opening your account using a private/incognito window. There are times the accumulated cache in the browser becomes corrupted, causing this unusual behavior. This mode doesn't save your web searches and site data. 

You can use the keyboard short cuts that I've listed below:

• Ctrl + Shift + N for Google Chrome
• Ctrl + Shift + P for Firefox & Microsoft Edge
• Command + Shift + N for Safari

If everything is good, go back to the regular browsing session and delete your temporary internet files. This will eliminate the corrupted junk files so your browser can start over fresh. Clear Cache And Cookies To Fix Issues When Using QuickBooks Online.  

Lastly, you have the option to manually import those missing transactions so these will add to your online banking. You can refer to this article for more detailed steps: Manually upload transactions into QuickBooks Online.
