Hello there, @stewild1. I’ll help you connect to your QuickBooks Online.
Before we go into troubleshooting, let's double-check that our current browser is up-to-date. This problem can arise when you're using an older version. I recommend updating it to get the most out of QuickBooks Online.
Now let’s perform the troubleshooting steps. Here’s how:
1. Refresh or restart your browser.
2. Log in to your account and try to open QuickBooks in an incognito or private browser. You can use these keyboard shortcuts to launch a new private window:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
3. If it works on the private browser, you can go back to the regular browser and clear your browser's cache.
4. Now, using your regular browser, try to access the file again.
