I am having the same issues, I can't seem to get any help from QBO support or find anything online about a possible outage or update or sorts. I can't do any invoicing or see past invoices it keeps saying unexpected error has occurred, please try again later. Also my home screen can't load my bank account information, etc.  Does anyone else have any information as to whats going on and when to expect things to be up and running again?     I have tried re-starting my browsers, and trying in incognito mode and neither seem to help at all.
