Hello there.

We always aim to provide the best experience when navigating QuickBooks Online to perform different tasks. I'll provide relevant troubleshooting to isolate issues that prevent you from importing transactions by batch. Let me walk you through the process.

I agree with @Chrea. You can access your company file using a private window, as this will avoid interruptions from corrupted cache files. Outdated data can cause the software to crash, get stuck on a particular page, or other unexpected behaviors.

You can proceed to these keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

Once it works, switch to your regular browser and clear its cache to update the website's preferences. We also recommend using an updated and supported browser to maximize your navigation experience.

Moreover, you'll want to generate custom fields to monitor specific information about your vendors and expenses that are most important to you. For more information, refer to this article: Use custom fields for vendors and expenses in QuickBooks Online Advanced.
