Wow - it's two years later and they are still working on this issue?  We have had our email notifications just flat out stop coming in the last five days.  We still receive the daily report of total funds coming in.  But we really need the email alert upon customer payment.  I do not have all day to stay on the merchant center manually checking to see who has paid.  Can you guys please work on a solution?  Also a lot of what is recommended on this boaed does not apply to QB desktop or the merchant center.  There is no place to turn on/off notification and the only email is the one listed in our profile.  I can only hope spending time on the phone with tech support will result in resolution - 30 minutes and counting....
