Brutal
I suspect the app and the web version don’t communicate. Our company requires us to update our password quarterly. When this happens I spend the next two months getting locked out of my mobile account, because it hasn’t registered that my password has changed. After months of frustration the app finally catches up, only to repeat the cycle of misery when the quarter changes again. If you have time sensitive invoices, make sure you can log in to the desktop version; or I’d suggest finding a better invoice processing solution with a solid mobile offering.
