Hi Xi3,
Welcome to Community! Missing transactions from your bank feed is definitely concerning, as year end is approaching. QuickBooks Online has usage limits that vary by subscription. However, you should be able to view all transactions in the timeline you've indicated. I'd be glad to assist!
If you haven't done so already, I recommend clearing cache on your browser. This will help to improve system performance and page loading times. If you're still not able to view all of the transactions, follow these steps;
1. Open your Settings ⚙ and select Chart of accounts
2. Click on Account history in the Action column
3. Open the Filter (looks like a funnel)
4. Use the ▼ dropdown menu to select a Date, or enter a Custom date range
5. Hit Apply
Should you require additional assistance, please don't hesitate to contact us.
Schedule a Callback: click (?)Help in the upper right > click Contact Us > explain your situation > click Let's Talk > choose Get a callback (Note: Callback hours are the same as regular phone hours.)
Social Media: Facebook, Twitter, and Instagram from Monday to Friday between 9 a.m. and 8 p.m. ET.
Feel free to reach back out if you have any other questions. We're always happy to help!
