Odd behavior when signing in to QuickBooks Online is sometimes caused by a browser-related issue. The stored cache can affect the performance of the program.

To rectify this, I'd recommend accessing your QuickBooks account via a private window. Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

If it works, let's clear the browser's cache. Doing so removes its stored cache to ensure the program performs efficiently.

You can also use other supported browsers as alternatives. 

Additionally, I've included an article that'll help you keep track of how your business is doing: Run Reports in QuickBooks Online.

I'm only a few clicks away if you need assistance completing your QuickBooks tasks. It's always my pleasure to help you out.
