That's not usually the case, alt-j_llc.
We can perform a few troubleshooting steps to fix this unusual behavior. It's possible that stored cache files are causing your browser not to function well.
Let's try to log in using a private browser since it doesn't store cache files. If it worked, we can clear your main browser's cache to remove piled up data that caused the behavior. You can also log in through other browsers.
On the other hand, if you are using the QBO app you can reset your app data. Just got to the Help menu and select Reset App Data. If the issue persists, you can uninstall and reinstall the app.
Feel free to post again if you have other concerns. I'll be around to help you.
Thanks for providing a follow-up and letting the Community know the steps that you used, @alt-j_llc. I'm also glad to hear that it's now working for you.
Should you encounter this, or other unexpected behavior, it's generally recommended to perform browser troubleshooting. As my colleague referenced, deleting cache files can help. Also, the closing of windows and restarting a browser can also help to improve performance.
