Let me share some troubleshooting steps so that you can utilize QuickBooks Online (QBO) smoothly and efficiently.
The issue might be caused by a data problem with your browser. At times, the browser stores frequently accessed data, which can result in unusual behaviors in any online platforms, including QBO. Let's access your account using a private browser by following the keyboard shortcut keys below:
Google Chrome: Ctrl + Shift + N
Safari 11 or newer: ⌘ + Shift + N
Mozilla Firefox: Shift + Ctrl + P
Microsoft Edge: Ctrl + Shift + N
Once it works, go back to your regular browser and clear its cache to refresh the website's preferences. You can also use the different supported browsers as an alternative.
