Thanks for your interest, @Kevin_C.  If you would kindly read the rest of this thread, you will see my original description of the issue, and you will also know that the problem has gone away on my end, although others have reported that it is still a problem.

The original problem is/was poorly-worded text appearing near the top of my invoices from QBO saying "You can pay now your invoice..."  That text was not configured anywhere in my QBO, and has since disappeared.  Other QB employees have responded that the developers were working on a solution, while others have tried to direct us to the invoice configuration sections of QBO to correct the issue ourselves.  I'm not sure what the truth is, but as long as that text is gone, I don't really care anymore, although others who still have this issue probably do.
