Hello there, @stoelk.
I appreciate you clearing the cache and cookies to fix the blank screen issue. Allow me to lend a hand and ensure this gets taken care of.
Have you tried switching to a different browser and updating the one you’re using? An outdated version could be the reason behind the problem.
Learn more about QBO’s supported browsers and other system requirements via this link: System Requirements for QuickBooks Online, Online Accountant and Self-Employed.
Make sure you’re using a supported web browser to access QuickBooks Online. Check out this article for reference: Discontinuing support for Internet Explorer and old Safari versions.
That should answer your concern for today. Get back to me and let me know how it goes, I’m always here to help. Have a good one!
