Appreciate the advice. 

Believe I mistakenly lead us down a rabbit hole. We use the same license # to access two separate companies. They use one purchased seat, we use the other. Neither of us can access the others' companies. Seems there are certain times when they are unable to access their bank through QB Payments. Not sure if the updates must be done on the host computer, as well as any other computers which might access the respective companies, or if it is something else that is creating this. Can you advise further with this information?

Thanks in advance.
