Transactions by date range are not working now in QB

I'll help you with the troubleshooting steps to get you back on business, @angelayu619. 

To start with, may I know which part of QuickBooks Online that date range isn't working? Any additional information would be very much appreciated, including a screenshot. This will help me identify how to accurately help you in any way I can.

In the meantime, we can open your QBO account and use a private window to narrow down the cause. Your browser may slow down because of frequently accessed resources such as cache and cookies, leading to unexpected behavior.

You can use the following shortcut keys to access the incognito window: 

• Safari: Shift + ⌘ + N
• Google Chrome: Press Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + N

Once everything's fine, we can clear the browser's cache to give the system a fresh start. You can also try different supported browsers alternatively. 

Additionally, you'll want to check this article that can assist with finding, viewing, categorising, and excluding bank transactions in QBO: Find, categorise, and edit transactions in QuickBooks Online.

You can find me in the comments if you need further assistance with managing your transactions in QBO.  Have a pleasant day ahead.
