Hello, @karezz.
Let's isolate this unexpected behavior by accessing your QuickBooks Online account using a private or incognito window. This way, we can see if this a web browser related issue. You can use any of these keyboard shortcuts:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Option + P
Once logged in, you can try viewing your Customers list again. Here's how:
- Go to the Sales menu.
- Choose the Customers tab.
- Select the customer's name.
- Hover your mouse in the Transaction List section.
If you're able to view all of your sales transactions for each customer, I'd recommend clearing your regular browser's cache. Also, you can use other web browsers.
Let me know if you have other questions about managing your customer-related transactions.
