I spent over an hour on the phone with an Intuit rep, trying various strategies to resolve this. No success. Later in the call, he brought a bills.com technical rep into the conference call, who tried a few things on his end. Also, no success. The only alternate solution I was given was to manually provide documentation to confirm my identity (scan and email/mail a list of various documents). I have no time for this, and there's no reason I shouldn't be able to verify my identity digitally; I'm pretty well documented in QBO itself, and otherwise! So I've given up, in frustration. I've canceled our trial subscription to the app. We will not be using Online Bill Pay.
