I've contacted Support on this same issue at least three times in the last few wks. Each time, I'm on the phone with them for at least 2 hrs with no resolve to the issue. So, unfortunately you're suggestion of contacting Support doesn't help me at all. I have a case number from Support this last time. But still waiting on hearing if the techs, that where it was last sent to,  were able to fix this issue. I checked today by entering the customer's card info and the box still pops up. Our company has been using QBs Online since 2014. We know how its suppose to work. When QBs switched to the new customer details form for us to fill out; I explained that when we click on 'check' as a form of payment, no box opens up to even enter the checking act information like it use to. I had asked Support about that too and they're just as baffled as I am about it. Very frustration to say the least!
