Hello, brandanbruce.
Thank you for taking the time to follow the steps outlined above by my colleague Mich_S and tying it together on multiple computers. This should work after clearing your cache since it works normally when you open or tries it in a private browser.
This issue requires further investigation; I recommend contacting QuickBooks Online Support. They have the tools to open your account and submit a ticket to investigate the actual cause of this problem.
Here's how:
- Sign in to your QuickBooks Online company.
- Select Help (?).
- Click Talk to a human.
- Enter your concern.
- Select Contact Us.
- Choose a way to connect either Chat with us or Have us call you.
I've also added this article about fixing an invoice payment applied to the wrong invoices for future reference: Fix a payment applied to the wrong invoice in QuickBooks Online.
