Adding bank account error

Thanks and welcome aboard to the Community, MikeMaggio.

I've checked here, and I'm unable to find any open investigation going on specific to your region. Let's start with some browser troubleshooting to determine if the problem is system-related.

Please access QuickBooks via a private browser to distinguish where the issue is originating. I'm adding the shortcut keys depending on what you're using:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Internet Explorer: Ctrl + Shift + P
• Safari: Command + Shift + N

If it works, I suggest going back to your regular browser and clear its cache. For your reference, I'm also attaching the article about QuickBooks Online system requirements, such as the supported browsers:

Get back to me if you need additional help adding the bank account, and I'll be sure to get back to you.
