While they do, it is best to get in touch with our QuickBooks Online Care Team so they can add you to our notification lists of affected users. Here's how to contact us:
That should get you to connected to our live support peers, @DaveinAZ. You can have our representatives add you to the investigation number INV-21697. Once added, you'll get live email notifications when an update is available.

If the private browser does not show the same hitch, you can continue doing your tasks in your QuickBooks Online account on a regular browser then clear your browser's cache. Here's an article to help you: How do I clear the temporary Internet files and cache?
Please update me on how this goes. I'm here to help you get things figured out. Have a great day!
