Thanks for getting back to us, kaye8.

I'll share with you some details on how we can isolate this issue. This way, you can seamlessly manage your customer with ease.

For the time being, there aren't any reported cases of customer lists in QuickBooks Online (QBO). Based on your description, it seems that the error is caused by the browser's collection of data over time from frequent page visits. To isolate this matter, you can perform some troubleshooting steps.

I'd suggest logging out and logging back into your QuickBooks Online (QBO) account. It refreshes the system and for the updates to take effect.

If this is not the case, I recommend accessing your account via a private or incognito window. It allows us to determine whether the problem is due to browser caching.

Using a private window helps us verify the issue, as this doesn't save any data files. You can utilize these keyboard shortcuts when opening an incognito window.

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

If it works, go back to your regular browser and clear the cache. If not, use other supported web engines to learn what computer and browser are needed for the best experience when using QuickBooks.

However, if the issue persists, I'd suggest getting in touch with our Customer Support Team. This way, they can pull up your account securely and further investigate this. Here's how:

1. Click the (?) Help icon in the upper right-hand corner of the dashboard.
2. Select Talk to a Human.
3. Enter a short description of your concern and press Enter.
4. Click I still need a human.
5. Hit Contact Us to connect with our live support.
6. Choose a way to connect.
