Here we are, two months after this original question, and still no resolution to this question -- besides, once you switch you cannot switch back.  Why wasn't there some kind of warning that if you switch you can't switch back?  My business coach switched this one day, and now I can't fix it.  The new invoices had features that were very advantageous for me.  This is EXTREMELY frustration.  And even more so is the answer that, there's nothing you can do.  Just wait until it rolls out to everyone.  It should never have been offered if it wasn't ready.  ESPECIALLY without a date that it would be fully ready.

Add this to my ever growing list of frustrations with quickbooks and their customer service.
