QuickBooks Online uses browser cache and cookies to run faster. Sometimes, these can cause unusual behavior in the system when there too much data in the file.
That being said, you can clear the browser's cache and cookies to isolate and fix the issue. Follow the steps to clear cache for your browser:
After clearing the cache, make sure to restart your browser.
As an alternative, you can use other supported browsers to have the best and most secure experience while using QuickBooks.
