My customers (all of them) are not able to use the view (download or print) buttons in the invoice link provided in the payment email from Quickbooks Desktop Pro Plus. The payment part works, they can view the pdf attached to the email, but the view/print/download buttons in the page they are directed to from the email link does not work.

When view invoice is selected a new screen opens that says "We couldn't load the invoice". The button then changes to "Invoice Unavailable". 

When download is selected text appears below the buttons that says "Invoice temporarily unavailable. We appreciate your patience"

When print is selected a new screen opens that reads "We couldn't load the invoice"

I just spent a frustrating hour with QB support trying to resolve this. In the end I was told to call Microsoft for Support. Has there been a resolution to this problem? At the very least, the link should be removed.
