I want to ensure you'll be able to access the payroll page seamlessly, @pviggy.
To access QuickBooks Online (QBO) without problems, we have to ensure that you're using a supported browser. To check the minimum requirements needed to run the program, please visit this article: System requirements for QuickBooks Online.
Once confirmed that you're using a supported browser version and you still experience the same thing, we can perform some browser troubleshooting steps. Let's begin with accessing your QBO account in a incognito browser. Private mode does not store cache files that might cause errors when accessing websites. Below are the keyboard shortcuts that you can use:
Ctrl+ Shift + N for Google Chrome
Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge
Command + Shift + N for Safari
If it loads successfully, you'll have to clear the cache of your regular browser to refresh the background processes and to have a clean slate.
